AnswerHub is a social Q&A platform - an engine that permits you to create highly scalable and customizable Q&A communities which integrate fully into your organization's web infrastructure. AnswerHub is a commercial software-as-a-service product from DZone, the company behind OSQA. Being a hosted service, AnswerHub is fundamentally different from OSQA.
AnswerHub is 100% brand new, built from the ground up for extensibility and scalability with all the insights we have learned from building and supporting OSQA - one of the world's most popular open source Q&A community systems.
AnswerHub delivers a multitude of new features such as theme support, social network integration, the ability to follow users, topics and questions, and fine-grained control over content access and moderation privileges. AnswerHub makes it easy to divide your social Q&A knowledge-base into "spaces" to keep it organized and relevant, helping users find answers to their questions more quickly and effectively. AnswerHub is a pleasure to administer.
Although AnswerHub and OSQA share no code whatsoever, it is a simple matter to migrate from OSQA to AnswerHub. One of AnswerHub's themes emulates OSQA so closely that many users won't be able to tell the difference.
AnswerHub is not software that you download and run on your own server, but rather it is sold as a hosted "software-as-a-service" product that lets you to get started instantly and frees you from maintenance headaches. AnswerHub is easy to extend with custom plugins, easy to style with Wordpress-like theme packages, and easy to integrate with a RESTful services api. SDKs for theme and plugin developers will soon be available, as will service api documentation and examples.
At this time (Jan. 21, 2011) AnswerHub has not yet been publicly released, but DZone is working with select partners on early-access deployments. If you feel AnswerHub might be right for you, then feel free to contact me. I would be happy to explore possibilities with you.

P.S. - I would also like to add that DZone remains strongly committed to continuing our support for OSQA as a powerful, reliable, open source Q&A community solution. In fact, we have recently added new development staff devoted exclusively to OSQA, and the SVN commit rate and issue resolutions have been climbing. DZone loves OSQA, and it will have our support for a long time to come.
