Need recommendations but lack friends? - The interweb is everyone's friend. Seriously, though, this site will take just about any input and it will spit back other things that you may be interested in based on this input.
For instance, I like photography, ice cream, and The Shins. I input this to the site and it suggested I may also like:
Stuff that seems to be kind of popular:
Keane, Jack Johnson, Portishead, Madonna, Bjork, Feist, Coldplay, Depeche Mode, Snow Patrol, Kill Bill.
Not bad. Many of my favorite bands are listed there, and it even knows that I secretly like some Madonna songs (oh dear God, did I really just post that on the internet for the world to see?!?)
Give it a shot.
