"Jump" (Your) Knowledge

You may think this is "just one more of those web page annotation thingies," but you'd be wrong. This newest annotation application, "Jump" Knowledge saves your jottings online, so you can e-mail your comments to anyone. Even if the web page you annotated changes, your comments are preserved on the new page so they're never lost. Not only can you e-mail your web-commented pages, you can blog them as well. I'm already planning some critical reading assignments using this tool!
