We just launched a stats page that gives a fun overview of how you and your friends are using FriendFeed. Here are some of my stats:
We calculate the stats based on the last 30 days of activity on FriendFeed. "People you find interesting" are calculated by looking at the entries you have commented on and liked. Top sites are calculated by looking at where your shared stuff has come from over the past 30 days.
Check it out, and let us know what you think!
