As part of my research to sync all social networking graphs between sites I wrote a little one-off thingy to add all my LJ friends to my Facebook, but I'm sure it missed most of you. If you didn't get a friend request from me, plz to be being my friend. Facebook's "findfriends.php" kinda sucks. Better than LJ, but could do a lot more.
Going to write Perl bindings for Thrift next, only tangentially related, but it'd be a good way to learn. Then an LJ/Vox Facebook App, using WWW:::Facebook::API, probably.
