Microsoft PageRank?

Checked out the new Live Search Webmaster Center, Microsoft's answer to Google Webmaster Central. It's new -- so new that I find it virtually useless. Since I presume it's in beta, I expect more improvements in the coming months. But curious that the panel displays something they call "Domain Rank".
