I suppose personally there are a ton of technical forums on the internet that are a great source of learning. I have picked up java and C++ for some fun and have found public forums to be invaluable in my education. If you are explicitly speaking of MMO-Champion, I would say no. While some discussion on here can be stimulating, you have to wade through a lot of horrible political or philosophical talking points and an unimaginable amount of logical fallacies. That being said, while foreign languages are something that I have an unfortunate amount of trouble with, I do think it is cool to see how progressed non-native English speakers pick up on English using forums.
