The folks at Pumacy Technologies put together a list of knowledge management blogs. This a great resource for finding thought leaders in the area.
After initially being missed by the authors, I ended up number three on the list. The ranking is based on the number of posts in August. I met their four criteria: at least 10 blogs posts (I had 35 in August), 10 comments (I had 15), a Google PageRank of at least 5 (I am a 5) or an Alexa Ranking under a million (I am 774,585)
Thanks to Jack Vinson for pointing out the list: A Study of KM Bloggers.
