StumbleUpon

Well, I've found a second black hole - StumbleUpon. When you sign up for this site, you check off your interests on a long list and you add a Stumble button to your toolbar. Whenever you click this button, it takes you to a random site within your range of interests. There are thumbs up, thumbs down buttons as well, and after you've explored the site a bit, you click one of those. Your thumbs up sites are saved on your StumbleUpon homepage, so you can retrieve them easily whenever you want to spend a little time off task. One of the sites I found might appeal to those of you who are intrigued by Jackson Pollack and are doodlers as well. It's kind of fun to swirl lines and blobs of color around the page. I don't think Primary Source would have any particular use for StumbleUpon, but as teacher I might play around with it to find good sites to use with my students. For example, they list interests such as Ancient History, Geography, Japan and so forth. Who knows what random but potentially worthwhile sites might turn up?
