Earthlink Feed Reader: I guess the cat got out of the bag before it really should have left the litter box, so to speak. Earthlink has been secretly developing an online and free feedreader and social bookmarking site. Arrington details how they were found and some of the salient features, benefits, weaknesses and styling. I personally like the clean interface of the bookmarking site but most of these del.icio.us wannabes tend to have clean interfaces anyways. There is also an Earthlink blog that talks about the recent discovery.
