I quote Television Tropes:
LJ is also, for unclear reasons, the most popular host for Russian-language bloggers; the Russian term for blogging is derived from the Russian name of LiveJournal. The Russian content on LJ is a lot more like the rest of the English language blogosphere, and a number of high-profile Russian politicians maintain LJs. The Russian-speaking and English-speaking side of LJ rarely interact, although LJ is now owned by a Russian company.
Well, shit, that explains a lot 8\/
