Front page is too busy. While base color scheme is nice and consistent, whoever decided on help/blog/login colors must be shot. Do the same to whoever spelled "this is the fastest .." all in lower case and highlighted with lime background.

Selecting German and clicking on Start brings me to the page featuring a photo of dude wearing what looks like an Afghani hat. Also bunch of text is in bold - this is really annoying, you should really ease off on neurolinguistics :)

The overall impression of first two pages is "amateurish", which means that I am leaving even before I had a chance to learn what the site is about. Work on your design, make sure it's as visually polished as it gets. Then poll people again, this time - regarding the functionality of the service.
