All of the tech blogs have been talking about this all week, but I thought it was worth sharing with you. Google has a new tool called Browser Size which shows you the size of the browser window for people who visit google.com. It's an interesting tool, which you can use to judge what people will see above the fold when they come visit your website. This could be extremely helpful to non-profits and beginner web designers who are learning how to build effective websites.
The tool allows you to insert your url and see a color overlay representing different screen sizes; however, I haven't been able to get it to work for me. Could be the network settings at work. Check it out for yourself at http://browsersize.googlelabs.com/.
