Bloglines - RSS feeds, the most internet tool ever! I read a whole ton of blogs on a weekly basis and am constantly looking for updates - now I don't have to waste any more clicking! :P I log in and check my feeds for any new items! Cool, eh?
Protopage - This is another handy dandy web based tool. Basically I can create my own page and add random "post-it" notes, link panes, video feeds, to do lists, etc.... What a way to stay organized! Now I can have this as my homepage and every time I open a new window I can access and read any important items I have noted to myself.
