Wow, we haven't been keeping this thread up to date; we're on version 2.6.1 now. We just launched integration with Facebook Connect yesterday evening, so new members can register with a single-click and existing members can do the same if they "connect" your two accounts on your profile settings page:

Here are some of the updates that have happened recently:

  • March 13, 2009: Launched ProSCORE and added the reviews tab to the product page
  • March 31, 2009: Added a twitter tab to the product page
  • April 30, 2009: Integrated with Facebook Connect and fixed long outstanding OpenID bug

We currently aren't using Facebook Connect for anything other than a simplified register/login process, but it does allow us to potentially do some cool things:

  • find your Facebook friends that are signed up on ProductWIki
  • post to your Facebook feed (with permission of course)
  • list ProductWiki activity of your Facebook Friends 
  • invite friends to ProductWiki to help out
