I had this idea almost 4 years ago and since my New Year's resolution is build it or let the domain expire, I went ahead and built it on Google App Engine with CherryPy because they both make making things fun.
Basically I wanted a way to have some lists handy that I usually end up converting to some other format, this is that. I'm going to be rich.

Great idea, very nicely implemented. Dude, I love that you don't even have a copyright message on the page, let alone any sort of licensing mumbo jumbo.

Thanks. If I can get the top Google spot for "List of US States" I'll be happy.

Nicely done, Andre.
A feature request (oh noes) and a remark:
1. Maybe add the number of items somewhere in the list? e.g. "Countries (150)"
2. listable.org (without the www.) points to a domain parking page.

Along with having the Add To Favorite, how about a “Mark as Verified” to add an element of trust to the data source.
