Foiled!
On a whim, because I don't want to wander the internet searching for housing, even though I really should be doing so, I tried to create a Livejournal with Superbus as the name. Taken. And not by a gladiator with a 14-inch-small-italian-sausage, but rather, by someone with a bit too much dirty laundry for the Internet.
On the bright side, superbus.blogspot.com is still free.
