Well I'm sure those interested in public arcs and RP will continue to go on and do that. I tried that last year for the first six months, and no longer bother with it now. It's not that I've never been open to people wanting to interject themselves into my non-existent character narrative, but having reached the limits of asking myself, "Dear God, what is all this derps right here," With the interactions that developed.
Once having reached that limit, I at first felt a degree of frustration, then accepted it as just the way things are. As such these days I find it far more enjoyable to live behind a metaphorical iron curtain of my own creation where I don't have to care what anyone else character is doing and they don't have to care about what mine are doing. It's an status quo I'm coming to enjoy given the alternatives, and an effective QA tool of sorts to ensure that any interactions I do participate in are with those players and characters that won't shit me immensely.
Frankly, I'm having more fun right now playing the game, exploring the lore, and writing a piece of fiction here and there than I ever did trying to roleplay and interact in public - which I use only now if I feel the need to act out a shift in character persona or opinion and agenda setting, then leave it at that.
I don't feel I'm alone in having gone this route, and as far as I can see unless you come within the area of an established RP social circle, clique, or group that's retreated into private channels and networks then I guess there's the only option of all the characters in one man corps, NPC corps, and isolated individuals that want to act out their solipsist fantasies in public.
