It's on purpose, like short selling. They are waiting for the wave of powerdowns from the hardfork to end. Nothing will happen until the "weak hands" or "disillusioned users" finish selling off and leaving. Then the sockpuppet army will arrive and start hyping desperately needed features again. You know, like being able to edit\delete your own posts, and maybe fairer voting, and a simple tip button, all while consolidating earning power and control into the witness features.

It's a pattern, you can watch it happen on a regular basis with bitshares\graphene\steemit.
