The main reason I did finally do this software upgrade is because the new facebook connect feature is confusing. While I think it is awesome, it is double and triple registering people with their real usernames, and because it does not use Open Graph, like the old facebook connect feature we had did.
We will lose many cool features with the new facebook connect, but it will still have more features than before. I will give a complete list of what it does once I complete everything.
