Take the Problogger Test at Daily Blog Tips. I only got a 70- what score did you get?
Curious where you stand as we head into a possible Page Rank update this weekend? Try SmartPageRank. I like the backlinks analyzer there as well. It lists pages elsewhere that link to you, including the PR of that page. You can also see whether each linking page uses “NoFollow”.
