MFP Groups...Dead, Dying or Thriving?

When MFP Groups were first introduced I thought they were a pretty cool idea. Now I'm not so sure. :huh:
I say that because it seems like GROUPS are dying off or already DEAD!!!!
I am a member of several groups (5+) and NO ONE, absolutely NO ONE, posts in them anymore.
What happened? Did everyone give up &/or quit MFP?
Is anyone else finding their groups dying off? Or are your groups still active & growing?
