Marking Up Webpages Like a Whiteboard
Firedoodle is a Firefox add-on that let's you mark up webpages like a whiteboard. Just like when you make a screen print of a page and bring it in photoshop, snag-it, or powerpoint to point out things on a page, you can do the same with this tool. You can save your work and also mark your spot on a page that you're reading so you don't lose your place. It's pretty neat, check it out for yourself.
