TweetVolume is rather limited (no link to charts, no search returns other than frequency), but quite fun, and does what it says on the tin: provides (unverifiable) volume data on words or phrases used in Twitter. It will be the Twitter fight tool-du-jour for bored Google jousters.
To add to the cornucopia of web 2.0 candidate comparisons, here’s a TweetVolume chart for five of the ’08 candidates.
What does it mean? Probably not a lot. I picked five so-called “front-runners” , whose names happen to be distinctive enough to merit use of surname only. Comparing Ron Paul would be problematic, because his surname alone is too common to make results meaningful, but to compare “Ron Paul” (398 Twitter mentions) to just “Clinton” or “Obama” won’t do either.
Whatever the (massive) margin for misinterpretation, Obama’s showing is quite impressive, and I am surprised to see such a huge difference in tweet volume between Clinton and Giuliani (or any of the three Republicans here).
