I recently received an invite code from Google to try out Google Analytics. It's a stats tracking system for your website. It is meant to integrate with AdWords to track which of your advertisements on Google are doing the best, but it works fine without. The Tour can explain it much better that I can, but it's definitely one of the best stats tracking systems I've seen. A tad buggy when tracking referrals, but lives up to its expectations besides that.
I finally got invited to help test the new Google Page Creator. This is an online page building tool to build simple pages to go with the 100MB of hosting Google provides. It's very easy to use, but not very powerful for those advanced users out there. This is definitely a web hosting service for your mom.
They provide a simple "file manager" where you can create simple pages based off of several templates, and the option of 1, 2, or 3 columns on your page.
On the actual page, you have the simple text options such as bolding and underlining text, changing the color, font, and size and such. You can enter HTML within "blocks" on your page, but you can't enter custom code outside of that, and you can't move these blocks around without picking another template.
You can check out the page I made. Also, check out the code. While it isn't 100% valid, it probably has to be the cleanest code by such a tool I've ever seen.
