how many Twitter services do we need when no one can decide if we even need Twitter Truer words were never spoken. True, there are many people who find Twitter eminently useful, but there are far more who can't seem to figure out what the hell it's for, and I suspect many at Twitter HQ of belonging to the latter group. There are a glut of startups right now that don't really do anything useful, but have had no problem getting funded. The investment model seems to have moven away from "where's the market going to be in 3-5 years" to "if we invest in a spaghetti website, a sailing-meets-geocaching website, a cake-delivery website, and a social media microblogging iphone app, then surely one of them will hit."
