50 most bizarre social networks

Places of worship

36. Sneakerplay
Kickin' kicks
If you love trainers rather more than is healthy, indulge in a spot of Sneakerplay. Here you can show off your trainers and even go head-to-head -- or toe-to-toe -- with other members, in sneaker face-offs. Or should that be foot-offs?

37. Xianz
FaithBook. Anyone? Anyone?
If worshipping trainers sounds frivolous, make friends with Jesus. The Xianz homepage trumpets itself as "the MySpace alternative for Christians! It's the Faith Based MySpace!" Now doesn't that sound like a barrel of laughs? Wait, come back!

38. Shelfari
Book 'em
From the good book to lots of good books: at Shelfari you can upload the books you have read and see them on a virtual shelf, add reviews, and make friends with other literary types. Personally we prefer books with pictures.

39. Zuda
Sequential art
Comics fans can submit their own comics to Zuda, pictured, and vote on the work of others. We're tempted to do some kind of patronising "Holy clichéd gag, Batman!" reference here, but we're not that cheap.

40. my.BarackObama
We've got a crush on Obama
Speaking of superheroes, the likeliest candidate ever to be America's first black president -- apart from Morgan Freeman in that meteor movie -- even has his own social network, my.BarackObama. The home page sports a spiffy red button for making donations to the cause, if you can spare a bob or two. Whether Obama gets in or not, at least Bush is out on 20 January -- and 30 seconds later the world will breathe a collective sigh of relief.
