Part of my duties as the self-proclaimed Father of Web 2.0 is to help spread the word and get people interested in Web 2.0. BlogBridge has just published a list of some of my favourite Web 2.0-focused blogs. Note that it's not a directory of all Web 2.0 related feeds, just a selection of feeds I visit regularly.
BlogBridge is an open source RSS Aggregator that I haven't talked as much about as I should've. It's a downloadable app, so that's probably why. I prefer Web-based systems. Still it's worth checking out if you're looking for a new RSS Aggregator.
