It could very well be a language barrier, but in fairness, I've had people comment in their native language and I've then used a translator to read and reply to them.
I've noticed a bit of a slump over the last 4 years I've been here, and you're right, it certainly seems to be connected to the markets in general. Hopefully we see a nice flood of people returning, and new people too.
Thanks for the comment though, I suppose it is perfectly normal, I'd say after a week or two I'll get back into the swing of things once more.
