I've created a proposal for a Q&A site for BeOS and Haiku users and developers here: http://area51.stackexchange.com/proposals/60601/beos-and-haiku
Please support it by voting for it, upvoting good questions, or asking good example questions. If the proposal gets enough support then it may become a Q&A site that's part of the StackExchange network!
What is Area51?
Area51 is StackExchange's system for proposing new Q&A sites.
What is StackExchange?
StackExchange is a large network of Q&A sites, where users can ask questions, answer them, vote and discuss them, across a wide range of topics. Its most popular site is StackOverflow which is used by many many developers worldwide, and for many it's their #1 technical resource. Other sites in the StackExchange network are also great resources for finding answers.
Why should I support a BeOS/Haiku Q&A site?
I believe that finding answers to BeOS/Haiku problems is difficult, especially for those not part of the existing community and familiar with its resources, such as the forums or mailing lists. The StackExchange Q&A sites are incredibly useful as questions are very easy to find, in a well-structured and moderated format. It can also provide more visibility to the Haiku project.
