You know what would be neat? If MetaFilter could show you a list of users who are similar to you, based on your favoriting histories, the tags on your posts, the tags on AskMe posts to which you've replied, etc. Or if MeFi matched up users who favorited each other's stuff a lot. Sort of like OkCupid's matching engine, but simpler—and not necessarily for dating purposes. [more inside]
Last Five Favorite posts from ___'s contacts & Last Five Favorite comments from ___'s contacts does not match up with Favorite posts from ___'s contacts & Favorite comments from ___'s contacts. I guess it's vaguely possible that this is because "Last" works on when something was favorited as opposed to when the favorited thing was posted, but the discrepancy is pretty large and I think there's a bug there.
