Well, I'm the only Russian speaker that's actually
voted so far
I also speak rather poor French (it will improve with time and study, I suppose) and equally rather poor Dutch. The only thing I can say for myself is that I can read rather easily in both languages, but speaking is a different matter.
If I were not bogged down with other concerns, I'd definitely be learning Finnish (an amazingly sexy language, IMO), as well as Arabic, Hindi, and Hebrew, but there are only so many hours in a day, I'm going to have to save these ambitious linguistic pursuits for a later time.
