Blogs: Have you tried BlogPulse?

I spent some time today playing around with the Trend Search tool at BlogPulse. Quite addictive I have to say.
In a nutshell, the tool allows you to enter up to three phrases to search for and plot a graph over the last month or the last two months showing the frequency the phrases turned up in the blogsphere. Sounds simple? It is and as I already mentioned, highly addictive.
I'll be heading back there....
