    I wanted to create a Q&A site for kids at home. Was struggling with osqa and django when I saw this and the question2answer setup worked just fine in less than 5 minutes as claimed. Thank you.

    There are some pretty nice options available to you when it comes to Open Source, I’ve listed the best 3 that I’m aware of:

    OSQA is an open source Q&A platform similar to StackExchange, definitely worth looking at if you’re considering open source.

    Askbot is also a Python Django platform modeled on StackExchange, so should be considered as well

    Django Brainstorm is again, a Python Django based platform developed by Sunlight Labs and can do the job also

    People may also want to consider a SaaS solution if you’re considering open source, as these solutions are automatically updated/updated/supported and require much less maintenance…but of course you have to pay for those perks:) Here is a list of powerful SaaS solutions that are also available for consideration. is a good service supporting some brand-name customers, serving a few different markets when it comes to Q&A interaction, worth looking at. provides a nice Q&A community platform, very user-friendly and a nice Web 2.0 look/feel. offers a clean Q&A experiece for either a community or for enterprises looking for internal collaboration.
