Blogpulse New Features Causing Meltdown

Story Text:
If we don't find something else to talk about other than blogs we'll lose a good segment of the TW crew today :) Jason Dowdell has a great walkthru of the new features being beta'd at BlogPulse. Problem is, when i tried to use the new Profiles feature I get a 500 Java error...
Presuming they manage to get it fixed, the profiles feature sounds very intriguing..

Permits a user to plug in the url of
a blog and get detailed information about that blog, including rank [available only for the top 10,000 blogs], rank trends, post trends, citations, citation trends, sources, and similar blog

Weather it's of any further use than vanity searches remains to be seen though...
