Interesting, looks like the profile photo is put in a box with fill resizing and then has the circle put on top, judging by my oddly widened appearance in the timeline vs my profile photo in upper right.

Should there be some advice when setting a photo on recommended shape / an avatar preview?

Also would be nifty to have blurbs use the social/Twitter keyboard with prominent @-sign to simplify talking to others.
