Semantic Overflow is a great way for the Semantic Web community to help one another with questions, problems and education. It was started in November 2009 using the Stack Overflow framework hosted by Stackexchange.
It’s still building, with 261 questions submitted and just over 450 registered users, about a third of which have enough reputation to vote. Here’s an example: Ian Davis of Talis asked What is a good elevator pitch for Linked Data? and got 17 answers.
Like the parent stack overflow system, semantic overflow is a blend of a forum, wiki and recommendation site. It lets user ask, tag and answer questions, but also allows those with a sufficient reputation score to vote on and even edit both the questions and community submitted answers.
The tradition way of asking technical questions of a community is the mailing list or a Web based forum. The stack overflow model offers many advantages, so I hope this site continues gain traction.
If you want to monitor the site for new questions, you’ll find the feed of the 30 most recently submitted questions useful.
