Of course, if your interests are wider than specific educational content you will want to share the other jewels of the web, many of which can be shared with your students. A trip to Wikipedia to see how a free, community-built encyclopedia works should be very fruitful - as long as it is not still overloaded (the perils of success). So rather that just read about a selection here, click your way to the Webby site and have yourself a trawl.
