At what point does $seo_tool that broadcasts to YASNs become counter-productive because everyone blocks or mutes you? I'm thinking specifically here about http://paper.li I now get 10 or 15 tweets a day that are copied to Facebook and Buzz saying "The $boring_topic Daily is out!" If these didn't come from a few people I respect and who occasionally make interesting posts, I'd just throw them and everything else they post in the kill file. paper.li is a moderately clever aggregation tool. But the auto-publish to YASNs feature is turning it into just more noise. And since people get upset by noise and eventually take steps to blank it out, the end result is not personal brand building but brand destroying. Perhaps the real problem here is that Twitter has become Write Only Media. It's one-to-many broadcasting where the only things reading it are automated tools. That makes it a distribution medium and layer (like RSS) and not something that is meant to be read by humans. Even as I say that, I'm reading *some* tweets in Buzz and in Facebook status updates and finding them useful and interesting. So just blocking anything coming from Twitter isn't the right answer. The problem is the signal to noise ratio is right down there in the thermal noise and the nuggets are few and far between.
