We just got a nice review from the folks at FreeLanguage.org, a good site with a collection of links to online language learning materials and resources in a number of languages (including less common languages like Catalan). If you're interested in reading a very nice take on what we're doing, feel free to check it out. The site has lots of of decent resources out there for other languages, including less commonly studied ones such as Catalan.

If you take the time to write a review or provide feedback, please let us know and we'll try to share it. We're continually working to add features and improve the service, and getting feedback (both positive and negative) is quite useful.
