i actually just realized, looking into your userinfo ,that you are pretty new to LJ, maybe that is one reason, why change again, doesnt sound appealing to you and some others.
you just got used to everything here , being familiar now, and then asking to jump again, is pretty much hard. Plus, undeniable, the fannish infrastructures that has been build here, are so convenient.

so actually, as i said before, there is actually no mass exodus, just a slow migration :)
