My bookmarks folder is a mess and I've got a brazillion (hehe) tabs open in Firefox. So I figure why not post a couple of useful links here? You may even find them useful.
ShinyFeet is a site that advertises unlimited email and file storage. It's also got some sort of photo gallery feature. Don't yet know what the catch is (probably advertising).
YouSendIt is a cool site that allows you to send a file (up to a gig!) to someone. Here's how it works. Type in a recipient's email address. Upload a file. The file is stored temporarily (for about a week I think) on the YouSendIt server and a link to the file is sent to the recipient. Again, not sure of the gotcha (advertising again?) but it's a pretty nifty idea.
Inquisitor is a(nother) search engine but has AJAX goodness and searches as you type. Pretty sweet. It gathers it's results from Google.
