Membership and avatars/profiles

Setting up Membership in conjunction with Q&A.

A couple of questions:

1) I wonder if there is a way to integrate avatars, or is it best to just provide links to the back-end profile in Wordpress and do it there?

2) Any plans for deeper social integrations and to make questions & answers tweetable/shareable on FB, like they do with WP Answers?

WRT #2, can I make a request for that?
