Hi, randomly wandering in: you may be interested in some of the links I've collected machine-translated from Russian, which seem to show some more stuff about SUP's future Cyrillic-LJ moves.

Hmm... Personally speaking, I do wish that LJ would port over more of these broadcast user tools to the English LJ side, because some of them are useful.

I'm not sure what effect DW will have on LJ. Maybe none. What will be more critical, I think (well, in my underinformed way), is competition with new hybrid-socialnetwork blogging sites, social networking software incorporating blogs (such as Buddypress), and microblogs like Tumblr. These I can see sapping LJ's audience.
