Open Source Solutions: Q&A / community capability: OSQAPosted: April 5, 2012
Open Source Question and Answer is a free, open source, python-based application that can be deployed to provide sophisticated community support to almost any online endeavor.
As they say on their site: “OSQA is the free, open source Q&A system you’ve been waiting for. Your OSQA site is more than just an FAQ page, it is a full-featured Q&A community. Users earn points and badges for useful participation, and everyone in the community wins.”
The system includes registration, posting with comments, and mechanisms to award participation points through interaction or community voting. The site is not unlike the familiar “stack exchange”, but is a competitive alternative (OSQA says LinuxExchange switched to OSQA from their platform).
I note that Udacity is using OSQA, and so far they’ve made lots of good choices.
