Nice blog and I see Yolango listed. This was a site I was very involved with developing (and still am -- it will be rethought after the beta period is over).
Please visit EFL Classroom 2.0 for all the language resources you can imagine. Thousands of members and we are dedicated to bringing free 2.0 learning to all -- specifically for language learners. Literacy teachers/students will also find lots there!
I don't have a specific resource for what you're looking for, but you might want to check out the following Diigo groups re: languages and learning. There might be some helpful resources there.
