Useful Twitter Tools

I came across a couple of interesting tools for doing Twitter analysis. The first is Twitterholic which shows you the top Twitter channels based on the number of followers. The second tool is called Twist. Twist is a tool that shows trends for certain terms and has some nice graphs. This is very similar to Google Trends where you can see the popularity of concepts over time. I went to Twist and typed in Kanye and got the spike I was expecting to see around the VMA awards.

I suspect that the Twitter collective and analysis of it have much more business value that subscribing to an individual channel.
