I'm subscribed to only about 15 feeds through Google Reader, which I refine every season according to signal/noise ratio. I'm also a big fan of Google Alerts, which I've found is a good way to find great articles that you wouldn't find in the echo chamber of most blogs, particularly those about programming.

Otherwise, I check HN and a couple other news sites. Most of the good stuff tends to rise to the top, and Google Alerts catches the good articles that don't get on the front page.
