Feedstats gives you stats on your FriendFeed usage
Although there's no doubt that Twitter is the current reigning social status update king of the hill, upstart FriendFeed is certainly a more than viable alternative. FriendFeed does everything Twitter can do and much, much more right out of the box, aggregating all of your feeds (including your Twitter stream) into a single unified online presence.
If you're already using FriendFeed, you might be interested in Feedstats, which shows you statistics about just what it is you get up to online, at least in terms of what you are funneling through the FriendFeed service. It also shows statistics about which other FriendFeed users you tend to interact with most, and which ones you are most compatible with, in terms of liking the same content.
Of course, all of these statistics are drawn from FriendFeed's openly available API, which means that you can snoop on your friends and see just what their habits are, as well. Or even better, check out a few A-list microbloggers to see just how much more social-networky than you they are.
