So. For someone who makes a living as a webmaster, I only just discovered Google's Webmaster Central. It isn't the be-all, end-all, but it's certainly got some useful tools, especially the Site Status Wizard. Also, if you haven't already been playing with them, check out some of the Google Gadgets; you can add a Google Map, a Wikipedia Search, local National Weather Service radar, and a host of other widgets (1531 to choose from!) to your web site.
