...you're seeing ads? Or rather, AdBlock is for you?
That's weird. I don't. I'm paid, but not permanent. Maybe something is malfunctioning.
Me, I blog at the band site, echo completely to Tumblr and Dreamwidth, then Dreamwidth forwards to LJ for me. It's a pretty good system. (Then I link to it from Facebook, Twitter, and Google+.)
That's for the big daily post. Smaller posts and comments and stuff are unique to each service unless I think they're funny enough to repeat for a different audience. Tumblr gets a bit of that, Twitter gets a bunch. Facebook very little, and Google+ none at all since literally every second time I visit the damn site, it force-refreshes every tab I have open, so I hate it. A lot.
As for feedback and interaction: LJ is still very high on the queue. It's Tumblr first, LJ probably second. Occasionally, on some individual post, I'll get more interaction on an LJ echo than on Tumblr - it's a different audience.
Anyway, that's what I do.
