Stack Overflow will be a questions & answers site for programmers. A reputation/experience points and “bagdes” system comparable to those of online gaming systems are what’s supposed to drive people to the service, making the intended audience (easily distracted programmer types) forget about their jobs and ruining their lives further.
In addition to giving social advantages to people who ask good questions and give useful answers, the innovation of the system is described as a mix of features from digg/reddit voting sites, wikis and forums. Most notably, the site is entirely usable for anonymous users, keeping it easy to ask questions quickly. The reputation-tracking accounts use OpenID.
The project’s blog is now offering a beta access code, giving anyone who’s interested access to the site before its launch next Monday. Having played with the site earlier in the beta stage, I can wholeheartedly recommend anyone who might need help with coding to take a look at this.
