First me, then Borderland, then Stephen Downes, then Alan Levine (not directly in that order). Alan Levine’s and Borderland’s posts tell me stuff about Google Reader I haven’t tried yet.
I’m more of a consumer than a producer at the moment, so it takes me a while to understand the benefit of being able to bind feeds together into new ones.
(Thanks to TeachingHacks for the link to Downes, and the post on the A-list blogger image at Kineda.com)
