Why twitter sucks for finding new music.Fair point, but it very much depends on who you follow. I follow fellow music nerds, industry types and so on, and get put on to plenty of cool new music. As with any medium, if you pay attention to mainstream sources you’ll only get mainstream content.
The signal to noise ratio for finding something cool in a content-specific area like music appears to be poor on Twitter right now. Last.fm/Listening to… updates, assorted services republishing data and people’s casual mentions of artist/tracks all mix up the reasons why a given update would appear in someone’s stream.
The tempting approach (taken above and by many others) is to sum up all of this activity and attempt to extract insight. The problem, of course, is that numbers trend to the most obvious uninsightful things and the things of real interest are buried and are easy for a machine to confuse with noise.
Solving that one is a bit more tricky. :)
