19 Bizarre Social Networks

Everyone and their mother is on Facebook these days, so where's a girl to go when she wants a little exclusivity? If she likes to crochet, Ravelry, the network for yarn lovers. The Huffington Post lists 18 other out-of-the-ordinary Facebook alternatives.

• MyFreeImplants: A site for women who want a boob job ... and men (aka benefactors) who are willing to pay for it.

• RedKaraoke: Wish you could sing your heart out every night? You can, without the bar tab, on this network, which lets you post your performances and rate those of others.
• Fubar: Another entrant in the nightlife category, this (questionably named) network bills itself as an "online pub" for those 18 and other that lets you send "virtual drinks" to other members.
• Line for Heaven: Your best source of Karma points on the web! Earn them based on your interactions with other users, and keep your fingers crossed: Get enough and you'll be made an "angel."
