New blog index based on the BlogShares db. Has a nice simple expandable tree format with 85,00 blogs in over 1100 categories. http://www.quacktrack.com

QuackTrack has a nice smooth interface, with tons of speciallized categories for browsing.

Just a little update for anyone who might have glanced at QuackTrack but not been back. My first post should have said 85,000 instead of 85,00. There are now more 105,000 blogs categorized into more than 1200 categories. A few improvements have been made to the interface as well. http://quacktrack.com
