What have you listed as an interest in your LiveJournal that isn’t shared by anyone? Is it misspelled or long-winded? I was surprised to find I was the only one who listed “alison eastwood” and yet quite a few LJers had listed “breathing oxygen”.
Gene-X but thats because its a pretty small webcomic that a mate of mine draws. Definitely worth a read if you like manga and don’t mind a bit of gore although not much.
Ultimate Fakebook (a localish band that recently broke up). This doesn’t really count, however, as there is a few with UFB and there is a UFB community.
Darktown House Band. (A local band that is no longer together.)
I took a cue from FilmGeek and did an LJ search on DTHB, but no one has that as an interest either.
I believe I’m the only person who has “Mightily Oats” (a Terry Pratchett character) listed as an interest.
Among a couple of other things (One being my husband’s nickname, so I’m not surprised that no one else has it listedn.), I am the only person who has “the Dallas skyline” and “being a rockin’ mama” listed.
aphrodite’s hymen - my friend’s stage name
dancemonkey - a friend’s blogging site
pompei’s grotto - a restaurant/bar in San Francisco
porntipsguzzardo - SimCity Classic cheat code- this is the most surprising to me
prohibition ale - local beer
samurai action squad - friends’ band
speakeasy brewery - maker of Prohibition
superbooty - friend’s band, also a bit surprising, they’re somewhat well-know around here
ubzorb - friend’s band
Space quarters, accidentally falling asleep, Boötes, and emotional flatlines are my four unlinked interests.
When I originally listed “shotting web”, it was unlinked. I was the first baby!!!
The only things that I have that aren’t linked are “Reading Reptile,” which is a local children’s bookstore that I would love to work in, but can’t because they’re family owned, and “Waldo Pizza,” a local pizza place that is incredibly delicious, especially the thin crust.
And FilmGeek, I’ve heard of Ultimate Fakebook, but obviously that’s because I’m local.
Australian baritones - namely Anthony Warlow and Philip Quast
fluffslash - slash that is, y’know, fluffy
family literacy (programs that provide ESL/GED and parenting classes for parents while their children attend preschool)
reflective teaching (when teachers actively reflect on their teaching and how to make it better, which is what I’m trying to do in my journal)
diet Coke with pineapple – my preferred beverage at a local soda fountain
Churchy La Femme & Porky Pine - characters from the comic strip Pogo Possum
Interior Desecrations - the title of James Lileks’ upcoming book (formerly a section of the Institute of Official Cheer)
I have “artisticity” and “passive existence”. Hm, I think I need to update this profile soon. This is me, by the way. My friend has “lotr actor commentary” and my other friend has “jello sticks”, “my sock puppet nigel” (she really does have a sock puppet named Nigel) and “the grigsby family” (I have no idea what that is). This person I don’t really know has “cyrenaics”, “nephalims”, and “you being you…”
I have “skipmagic” listed. All alone it stands–you uninteresting bastards. 
It’s not quite the same thing, but there are 15 people interested in getting UncleBill’s wife pregnant (i.e. GeoBabe).
I’ve got Broadway Beanery (a coffeehouse I frequent and have mentioned here) and Max Racks Cards (something I collect that no one ever seems to know what I’m talking about).
I have boozy barbeques, which are, basically, the kind of parties I hold at my home. Also in that category, I have drunken revels and ale jams.
I was rather shocked that no one has growing older and wiser, but 483 people have plastic surgery listed.
And I’m pretty sure that no one else in this world shares my fascination with ricardo montalban’s chest.
I’m the only person on LJ who lists Chaucer’s poems “The Parliament of Fowls” and “The Book of the Duchess,” and the only one interested in Cardinal Wolsey’s biographer George Cavendish and seventeenth-century playwright Elizabeth Cary.
And the only other listing of Elizabethan historian Raphael Holinshed is a community that I manage.
examines post Wow, I am such a nerd…
I have Chris Kamara (soccer pundit) Hopback Summer Lightning (beer), Henk Helmantel (artist), Jeff Stelling (soccer pundit) and Peter Lipton (philosopher). Oh, and Scots Pines (trees).
“One eyed pimps” and “whiny girls.”
I had fun with my interests list, and mixed things like “Kinky sex” and “black tar heroin” in with “Going to church.” There’s also a few real interests in there, but they’re too boring. On a side note, I find it disturbing that I’m not the only person who has listed “midget hunting.”
