I would like to see Connections give us the ability to present the user with a "Log In With (Facebook|Twitter|LinkedIn)" button.  Let us utilize an existing social network instead of having to build another one.  This is obviously for public facing Connections deployments.  These existing social networks already have user self-service and a much more mature community of users than any new Connections based site will generate in it's early stages.  If a Connections public deployment were just another app hanging off of the existing public networks, adoption and inclusion of public people would be much easier.  I saw this in a Portal Next demo, and think this will be great to bring to Connections.

 

I blogged more detail here:
