I'd probably go with heavily customized standalone wordpress setup. But that requires time to set up and tune and tweak, which I do not have... So for now I'm waiting till inapt LJ management pisses me off enough that I finally make time for it and move. Or that somebody develops a good blogging platform with same strengths in community building as LJ, but for the last 10 years it didn't happen, so I'm not very optimistic.
