Livemocha's problems start with actual errors, such as incorrect translations, and run the gamut through poor video quality and feedback written in a language that the learner does not understand.
That's not to say Livemocha doesn't offer value to anyone.
Some are drawn to grammar, while others prefer listen-and-repeat exercises.
Livemocha offers free and premium online learning courses for over 30 languages, and claims to have attracted more than 4.8 million registered members from over 200 countries to date.
Its interactive courses include practice with native speakers for natural development of practical language skills.
It offers content in an impressive number of languages38 and counting, including a few lesser-used tongues, like Icelandic and Esperanto.
Unfortunately, Livemocha used to be totally free, but now the most popular languages for English speakers (German, Italian, Spanish, and French) are not, costing per month or 9 per year.
Conversation Exchange makes it really easy to find someone to help you learn a language.
