Finally, a highly pragmatic Web 2.0 service -- Extratasty is a social drink recipe site that lets you find new mixed drinks (or remember the ones you learned and promptly forgot) by search or by tag, see what newfangled concoctions your friends are trying, and rate recipes you've tried as well a see others' ratings. It's got a cool feature that takes the list of ingredients in your bar and narrows the search subset to drinks you can actually make with the materials you have at hand. I vote this tool Most Likely To Be Accessed Repeatedly At Web 2.0 Launch Parties.
