Blogpulse: Still in testing phases (patience, please?) is a totally new feature called BlogPulse Profiles, which adds metrics to the top-ranked 10,000 blogs, based on citations, posting and linking behavior.
Randy: I was happy to find iBLOGthere4iM in the top 10k, just barely. The RSS Blog is not in the top 10k, even though my own metrics show a lot higher readership and in-coming link count I hope they take the lid off the top 10k blogs only, as this could become the replacement for broken Technorati.
