Twitter provides a list of the top 10 trending topics, but this seems minimal. Does someone maintain a larger list?
An obvious way to do this: track 1000s of tags (+ let anyone add more) and count the number of tag appearances in the last 15m, hour, two hours, six hours, etc, and then report on the most popular tags for these periods. -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology.
