What is a Question & Answer site?
A Q&A site helps your online community to share knowledge. People with questions get the answers they need. The community is enriched by commenting, voting, notifications, points and rankings.
Why offer Q&A on my site?
Your members will enjoy the interaction that Q&A enables, and will visit your site more regularly. In addition, many web searches are questions, so Q&A content will attract search engine traffic.
