Rosetta Stone?

I've heard of this program for awhile, and since I'm a language nerd, thought I'd babble on for a bit about it.

Rosetta Stone is an extremely popular foreign language software. It comes in a billion (okay, maybe 30ish) different languages. It goes through basic grammar and vocabulary in the voice of a native speaker, which is awesome. Another part of it that caught my interest is that it corresponds with state and national standards for ESL.

I haven't used it yet, but if you're interested, check it out.
