Bringing Order to Twitter Chaos: Twylah's Topic Tracker. There's no shortage of services that take content from the Twitter firehose and present it in a different way.
But one caught my eye recently, because it's doing something I'd always hoped a really good RSS aggregator would do: track topics. Nobody ever built the RSS topic tracker that I'd dreamed about. It's not a technical problem, more of a demand one. As you all know, the Web has evolved over the past 5-10 years into a very social tool. People prefer to follow (= track) people, more so than follow topics. Social Media Facts: Retweets passieren gleich oder gar nicht (und sind selten) Your.flowingdata / Capture your life in data.
