If you have a minute, check out http://www.bubbl.us. It's a pretty cool Web-based productivity application for diagrams, brainstorming, etc. This is the type of Web-based app that the world has been warning Microsoft about for some time (i.e. Google Apps).

Also, check out the new release of Google Analytics, something every marketer/business owner/Web site operator should find the time to do. Google just released a new version and the reviews are starting to come in. Check out reviews by beconfused, Mashable, and Mydeology. All seem to be relatively positive, save a few errors that still remain in the new site.
