I can only find a few that have more than 10 submissions:

dustincurtis.com (dcurtis)

danieltenner.com (wheels iirc)

blog.last.fm

balsamiq.com

sivers.org

netflixprize.com

steve-yegge.blogspot.com

Most of the other ones are either mainstream or have very few submissions.

If you want the list of one-offs and infrequent but high ranking sites let me know.
