After trying Duolingo a bit myself and seeing my family members try it, I've become convinced that Duolingo is worse than doing nothing, because it does a much better job of convincing you that you're learning than it does actually teaching you.

The courses vary a bit. The Welsh course, for example, is not that great. I have heard that off both serious learners and native speakers.

I've found it fairly useful for picking up other alphabets, as opposed to languages.
