I use Google Reader to plow through about 500 feeds (mostly marketing or tech related) and publicly "share" items that I find particularly interesting throughout the day.
If you’d like to get into the whole RSS or syndication thing but don’t have time to read through a bunch of feeds, you can subscribe to (or just visit) my shared items page. Consider it a "best-of" the affiliate, search, performance and tech marketing universe.
