As you might imagine, my list was a bit large:
????????, Aliens·&·Predator, Aminals, Bay·Area·HookUps, Beyond·Wrong, Bizarro·World, Bondage·A·Go·Go, Book·of·Lists, Bumper·Cars, California·LJers, Captain·America, Comix, Community·Crack, Crisis·Event, Fantastic·Four, Gamma·Reactions, Green·Lanterns, House·of·Happy, House·of·Skin, I·Be·Moody, I·Need·to·Get·Laid, JLA·Satellite, Kiss·the·Chef, LJ·Booty!, Matrix·Theory, Meme·Express, Mighty·Avengers, Motel·6, Multi·Genre·Fandom, Mutant·Mayhem, Naughty·lil·Devils, New·Providence, Odd·Sex, Oooh·Shiny!, Order·of·the·Bat, Photobugs, Power·to·the·People, Public·Transit, Renting·Reviews, San·Mateo·County, Sanity·Cafe, Ship·of·Fools, Slaves·to·the·Box, Sons·of·Krypton, Sporky·Reviews, Stark's·Armory, The·Argument·Clinic, The·Library, Unreal·Tournament, We·are·Borg, Webheads, Weirdfolks, & Werewolves·Howl
Took about 15 minutes to edit all that. I keep a list of them in a text file but they're not usaually in alphabetical order; got them divided by category. Exact count I usually avoid but I think that's about 53 or close to it.
I figured since I had this handy and I advertise the things individually anyway...why not just post the thing as a mass ad?
