They’re doing another ranking of Language Blogs this year, and are inviting nominations. The deadline for nominations is July 6th.
While I’m at it, let me repeat what I wrote about the Bab.la site earlier this year:
Bab.la has a large number of relatively simple series of exercises that varies by fluency-level. You can access them with or without registering. One nice advantage of registering (which is quick and easy) is that you can very easily create quizzes of your own. Creating these kinds of quizzes, under teacher supervision, could be a nice assignment.
In addition to this kind of language-learning, the site has created a nice map of world languages.
