Snazzy Maps - Color Schemes for Google Maps

I whipped up the site last week and it's been getting quite a bit of traffic this weekend (by my standards). I created it after I found out that you were able to do this to Google Maps and I was looking for some solid examples.

Some of the planned features I have are:

1. A tool for creating these styles. There are a few out there but I'd like to take a crack at creating a better one.

2. Ability to register in order to favourite certain styles.

3. Add an RSS feed.

If anyone has any suggestions I'd love to hear them.
