Filter Feeding

Everyone is a filter feeder. We have filters built from our culture, our society, our languages, and our parents. Our knowledge and self-image is the result of this filtering of the world.
Of course there are many people who filter the ideas of other people. News announcers, teachers, politicians. Most anybody with an idea is building off of the filtered information of others. Bloggers filter thier filtered world into the general mish mash of things (ie the web). Technology like Google lets you filter the web through specified terms, while services like Blogwise and blogSearch let you filter the filtered information of other bloggers. Modern filter feeders are still just standing on the shoulders of giants.
