I've already shared my OPML with Dave Winer's new service. Opens tomorrow. TechCrunch has the details. If you can't wait, my current feed list is on NewsGator (it's a Web service so you'll always see the latest list here). Two weeks ago I deleted all my feeds. I'm already back up to 99 feeds. Will be adding more over the next week. I've raised the bar to get added to my list, though. I want to increase the geekiness factor of what I'm reading and get away from the more marketing and business oriented blogs. Why? Cause I want to focus on people building software, since that's what I'm interested in most.
How do you pick feeds to subscribe to? How do you clean them out?
Update: Dave Winer says "it's an instant hit" and gives more details.
