I was perusing Yahoo Pipes today (gotta love it) and was somewhat shocked (and impressed!) to happen upon some 70-80 custom Engadget feeds. Users have created custom feeds for everything from honing in on Apple and Wii and BlackBerry news to combining Engadget and Gizmodo into a single, mammoth gadget news feed. But oddly enough, despite our vaguely controversial decision to post Apple and iPhone-free versions of our classic and Mobile feeds for the sanity of many over-saturated readers, the many requests for a Microsoft-free version of Engadget have still gone unfulfilled by the user base. Perhaps more surprising still, no one’s bothered to build a feed that filters out my posts.
