A handful of robotic news aggregators have taken over TweetsNet… Twitter users that spew volumes of URLs an hour, which makes them appear to be on top of whatever is new. I’m planning to exclude them by algorithm (just the raw number of tweets is a good clue, but they also usually follow few people), but for now I’m excluding the big ones manually.
The idea of Tweetsnet is to leverage smart people, not dumb robots.
