I know there was some talk of an aggregated page of all my friends posts -- where did that go in discussions?
Also, I was wondering if there were any protections against friend addition abuse. Right now it looks like a malicious user could just try to invite 400 users at once, yielding 400 unwanted emails at a time. Maybe it would be interesting to have a daily friend update email instead.
Additionally where did progress go with linking friends with invites? If I invite someone to join a site I like they should automatically become my friend when they join, no?
