Pondering the prevalence of various languages.

So what's the deal with all the russian language on this and other web journals? I find it odd that english and russian seem to be the only main languages represented in the journaling community in general. English I get, because duh, it's mine and know my own culture well enough to hazard a few guesses as to why we find it so popular. I do not, however, know the Russian culture, nor why they seem to enjoy blogging as much as we. Perhaps more poignantly, why are there no other languages represented in things such as trending terms? Are there other major journals/blogs about that cater to specific country web suffixes, so I'm just speeding on by them without being aware? I can guess there is a Chinese equivalent or two behind the great firewall, which none of us would ever, ever want to use due to stringent speech policies, but what of other places? Dreamwidth.fr or some such?

Also, if perhaps there are specific language sites for journaling and whatnot, why still so much of the Russian bloggers? There is a mystery here, perhaps easily solved, and I am intrigued. I love languages and mysteries, so this seems apt.
