I noticed a lot of you guy's and gals in the Post Your Desktop thread are using Last.FM.
Now, I consider myself to be as much of a girlfriendless tech/music geek as the next girlfriendless tech/music geek, but I don't quite understand the appeal of Last.FM. All it seems to be is a music-centric version of Twitter (which I also don't understand the appeal of), tossed in with some of the recommendation features of something like Pandora.
I loved Pandora when it first came out, but I started to get bored with it, because it just recommended predictable stuff that "makes sense" relative to my chosen favorite artist. "Hmm..so you like Yo La Tengo? Then you'll probably like the following songs by The Velvet Underground, Pavement and The Violent Femmes". The reason why I love WFMU so much is that musical curveballs are constantly thrown at my ears by most of the DJs I listen to, and generally, I like what I hear. And I don't get the feeling that said curveballs are eclectic for eclecticism's sake, which is why I hate Radio Paradise and any other radio station that proclaims itself "eclectic" (the other day at work, my coworker had RP playing on his computer, and I had to endure the sheer ridiculousity of hearing Joy Division's "Digital" played back to back with The Belle Stars "Iko Iko").
Maybe I'm an elitist, but I don't trust the masses–even (or rather, particularly) the trying-desperately-to-be-hip Web 2.0 masses–to recommend music to me. Does Last.FM have anything to offer to someone like me, in that case?
Also, I've wondered about how the scrobbler plugins in iTunes handle non-music things like Podcasts. Since I listen to more podcasts on my computer than I do music (that's why I bought a friggen iPod, duh.) it would be pretty dopey to be constantly updating my Last.FM profile with the last 20 Poster Children podcasts I listened to.
Sell me on this!
