50 most bizarre social networks

Bad behaviour

41. Smoking Passions
Smoke 'em if you got 'em
Marginalised by society, hounded from pubs and clubs, the yellow-fingered stinky cancer-puffers can finally feel loved again at SmokingPassions.

42. Gaambol
Play your cards right
The growth of online poker and gambling gives rise to Gaambol, a network where you can upload hands from your games, and blog about how you played those hands. Doesn't include Solitaire, sadly.

43. Coastr
Down the hatch
Finally, a niche network we can see ourselves joining! At least, we would join beer network Coastr if we hadn't hocked our computer for beer money. So we just went to the the pub instead. It's similar, but without the random abuse from strangers. Oh, wait...

44. AfterTheClub
Bangin' beats
If you're on one every weekend, check out AfterTheClub. It's a network for gurning mentalists with rubbish taste in music -- only kidding, clubbers.

45. PositiveSingles
Get your coat, you've pulled
So we've smoked up a storm, drunk ourselves into a stupor, and now thoughts have turned inevitably to the carnal. PositiveSingles is a social network and dating site for people with sexually transmitted diseases to hook up with other people with sexually transmitted diseases -- complete with drop-down menu listing what you're 'living with'. The Internet as a conduit for the socially marginalised to find meaningful companionship, or a breeding ground for some kind of super-Herpes? Frankly, this one just leaves us scratching our heads. And our crotches.
