Any application that lets you “friend,” “follow,” or otherwise observe another user should include a prominent (and silent) “PAUSE” button. I think users of apps like Flickr, Twitter, Facebook, LiveJournal, Delicious, and, yes, FriendFeed, would benefit from an easy and undramatic way to take a little break from a “friend” — without inducing the grand mal meltdown that “unfriending” causes the web’s more delicately-composed publishers.
