Yes, there's a limit to what users will tolerate. A system that is too insecure would not work. But the virus threat needs to be real to discourage piracy.
Ultimately, users do care about an OS with lots of software available. Many users will put up with some security threats to get that.

It would be sort of like this Facebook app:
The difference though is that people would not sign up requesting they be made famous. Rather, the service would do it without their permission.

Imagine for example a service that indexes open source code and provides such a visualization in the form of gardens. A non-programmer could quickly examine and compare the gardens for some competing open source software applications.
Bad smells in the source code would manifest themselves in the form of a poorly maintained garden.
You could also show code evolution via an animation of the garden over time.

"This paper presents a 3D visualization approach which gravitates around the city metaphor, i.e., an object-oriented software system is represented as a city that can be traversed and interacted with: the goal is to give the viewer a sense of locality to ease program comprehension.
The key point in conceiving a realistic software city is to map the information about the source code in meaningful ways in order to take the approach beyond beautiful pictures.
We investigated several concepts that contribute to the urban feeling, such as appropriate layouts, topology, and facilities to ease navigation and interaction.
We experimented our approach on a number of systems, and present our findings."
So why not consider "Lifehinting"? The idea here is to give clues as to what your life is like.
For example, you could do this by an algorithm that transforms a lifecasting feed into abstract animations, perhaps resembling VisualID Scenery. Similar sorts of activities would result in similar sorts of abstract animations.
After a while of doing this, your friends will start to get clues as to the sorts of things you do -- at least, for those activities that they are familiar with.

Study Stickies allows you to take notes (stickies) from books as well as online resources (e.g., pdf/html documents, videos, etc.).
The vision behind Study Stickies is two-fold:
- it allows people to take notes for themselves for easy browsing/search; and
- these notes accumulate allowing you to learn from others.
Imagine for example getting stuck on page 147 of your algorithms textbook or SQL reference. You might then see if others have made any insightful stickies for that page.

Another approach would be to build a custom human computation game for your startup to promote your startup in a more domain-specific way.
For example, if you are building an online video site, then you could provide a game similar to the ESP Game but adapted to video. Not only would this give you useful data to improve video search on your site, but it would also provide an engaging form of advertisement for your online video startup.
In a friendly, high-speed presentation, Will Wright demos his newest game, Spore, which promises to dazzle users even more than his previous masterpieces. Here Wright encourages users to create not households, as in The Sims, or cities, as in SimCity, but the entire universe, from single-celled life forms to galactic physics. While guiding us through his mesmerizing beta, Wright shares his thoughts on Montessori schools, Darwinian theory and long-term thinking, emphasizing, throughout, that Spore is not so much a game as an opportunity for discovery -- "an imagination amplifier."

NeuroSky has developed a cost effective bio sensor and signal processing system for the consumer market. Our wearable technology unlocks worlds of new applications such as consumer electronics, health, wellness, education and training.
The neurons that comprise the brain work on electrical impulses. The last century of neurological research has shown us that brainwaves of different wavelengths indicate different emotional states, like a focused awareness, a meditative state, or drowsiness. Brainwaves have been used in medical research and therapy for years. We're bringing it to the consumer world.
Adding this technology to Justin.tv would allow viewers to get into the lifecaster's state of mind, thus making the lifecast more interesting to watch.

It is important to have a "chat schedule" for each blog post. For example, you might announce 3 chat sessions, each 20 minutes long, for a particular blog post. This sort of schedule is important because you would like to have a reasonable number of people available for real-time chatting.

* really new subreddit: accept only urls that are not indexed by google yet
* no longer there subreddit: accept only urls in the Internet Archive that are no longer functional
* give them a chance subreddit: accept only urls with low pagerank
* crawler subreddit: can only submit a url that is linked to from one of the urls on the front page of the crawler subreddit
* domain subreddit: accept only high level domain urls (e.g., http://cnn.com but not http://cnn.com/...)
* reddit user subreddit

Our software takes a large collection of photos of a place or an object, analyzes them for similarities, and then displays the photos in a reconstructed three-dimensional space, showing you how each one relates to the next.
Note that the software actually identifies the positions of the cameras that took the pictures in the collection.
So in fact, you can use this approach as a tour guide, taking you to places from which many pictures were taken (i.e., the positions of the cameras).
Imagine for example walking around a city while a device points you to nearby places from which many pictures were taken and orienting you in the direction of the often photographed scene.
Such a device could take into account context (e.g., time of day, season, purpose of the photograph, etc.).
The Hug Shirt is a shirt that makes people send hugs over distance! Embedded in the shirt there are sensors that feel the strength of the touch, the skin warmth and the heartbeat rate of the sender and actuators that recreate the sensation of touch, warmth and emotion of the hug to the shirt of the distant loved one.
From the Lover's Cups web page:
Lover's Cups explore the idea of sharing feelings of drinking between two people in different places by using cups as communication interfaces of drinking. Two cups are wireless connected to each other with sip sensors and LED illumination. The Lover's cups will glow when your lover is drinking. When both of you are drinking at the same time, both of the Lover's Cups glow and celebrate this virtual kiss.
After all, if potential customers are likely to see your product via personalization, why bother with paid advertising?
For example, effort could be determined by looking at how much coding gets done each day. You would see your percentile rank among single founders in terms of this and other measures.
Effort isn't everything, but having that intense motivation that you find in multiple founder startups will probably help.
This could also be useful for suicide prevention. Imagine Google doing this with gmail to keep its users mentally healthy and safe. Signs of depression would be reported automatically to mental health professionals.
* allow viewers to control imaginary friends who can interact with Justin; only he and the viewers would be able to see and hear them.
* have one channel that gives the most interesting video among all other channels in (near) real-time based on user feedback (e.g., in the chat rooms)
* a search engine for clips based on associated chat text; yes, the chat is pretty noisy data but I think you will get interesting results anyway
* imagine using justin.tv to augment your mind, taking advantage of the intelligence and knowledge of your viewers
* use justin.tv as a way to interview people for jobs
* when Justin meets someone for the first time, viewers can show flashbacks from Justin's life to give a first impression (and the choice of flashbacks would depend on the person he is meeting for the first time)
* have a prediction market about all sorts of short-term events (e.g., in the next day/week) in Justin's life
model airplanes with people who would like to fly them remotely via
the web from the comfort of their homes.
A video camera would transmit live video from the plane and/or the
The owner of the plane would be responsible for the safety of the
plane. If flight inputs coming in via the web put the plane in danger,
then the owner can override them temporarily.
Flight inputs may come in from one person or a combination of people
via some voting mechanism. Users who would like more control over the
plane would pay more.
For example, you could consider the IQ of the creator of the site as well as the IQs of people who link to the site.
The creator of a site would have a greater incentive to undergo IQ testing so as to have some chance of ranking highly.
Not sure what sort of incentive you could have for encouraging people linking to a site to undergo IQ testing.
Listen is a game that lets you tell others what you think about music. It also lets you hear what other people think about music.
Music is a subjective form of art. We all have our own unique experince when listening to a song. Even though you might think that "Hangin' Tough" by New Kids on the Block is "explosive and revolutionary", your friend may think it's "cheesy and annoying". Play Listen Game and see if the world agrees with you!
Now clearly, this idea can be used to give first impressions on all sorts of things -- not just music. And so why not apply it to online advertising? Not only would this motivate people to look at ads very carefully, but it would also give advertisers meaningful feedback on their ads so that they can improve them.
The intuition here is that these images will have some impact on your thinking patterns.
So the idea is to see whether you are reacting as a typical human being would when viewing these images while playing chess.
For example, some images may have a negative effect in tactical positions.
One can have players play a against a computer every once in a while without telling them to see if they are cheating.
So how would you build one? Where would the ball look generally? How would you provide stable video in the presence of a spinning ball?
Functions are written using high-level English. Each such function along with the input can be viewed as a two-player game.
As with the ESP Game, when two players agree on the output, they would then move on to the next function (possibly from a different program).
As with the ESP Game, players can pass if they are presented with something that is difficult. And "programmers" get feedback on what parts of their program caused problems. They can try rewriting those parts.
Issues include quality control, debugging, profiling, and refactoring your program into parts that are easy enough to be games.
I suspect that many people would like to invent new ones as well.
So how would you build a twisty puzzle construction set program to help them do so?
What sorts of constraints would you put on the puzzles so that the program can provide instructions to build them for real?

Religious people are careful about their actions because they believe that God is always watching them.
With lifecasting, you are being watched all the time also. In essence, the viewers play the role of God.
The reason being is that cheating adds a new dimension to these games, namely strategy.
So in the game for identifying beautiful images, you can try to get into your partner's head based on the results of previous image pairs. This adds a new dimension to the game that is missing in the ESP Game.
So instead of combating cheating, why not encourage it explicitly by providing features to help players cheat? For example, in this beautiful image game, one can show the results of past image pairs while the game is in progress.
Even in the presence of such cheating, one may still get lots of useful data for subjective problems. In fact, one may get more as the games would have a new dimension to them.
