Another option for BoingFilter is to grey out (or collapse) posts that don't meet your criteria. At any rate, I don't think BoingBoing posts enough content to make filtering worth it. We're talking an average of, what, 10-15 posts a day? It takes less than a minute to scan the titles on a given day and filter visually with a single eyelid.

I'm of the opposite approach, I'm interested in being flooded with more content. More authors, more content on BoingBoing. Seven or more other authors to continue diversification of the content. Capable authors out there with adjacent angles on the popular themes of trash-collecting, Japanese publicity stunts, QTVR, SARS, sci-fi and copyright law. Maybe one new author that did his own experiments in trying to reanimate dead spiders and glue dragonflies together. Or a WiFi-crazed lumberjack that could go on a quest to chop down telephone poles and put a photoblog in his axe.
