Here's the latest example of bots drowning out actual posts: http://tntluoma.com/temp/TrendBots.png (screenshot)
Of 11 visible results: 4 are actual content (although 2 are ReTweets, which is another issue altogether, but at least they are humans) 7 are bots. Almost 2x as many bots as actual results. IMO, "trend bots" should have to be registered with Twitter (they say what they are going to use their API access for, right?) and should excluded from Twitter search. If people want to FOLLOW one of the Trend bots, fine, but they are choking the usefulness of the trending topics list and with nothing but echoing noise. It's getting as bad as trying to go to Google to find hotel information. TjL
