Is this community dead already, and what does that mean to MDSD?

I've noticed that despite the increase in members, the activity is steadily decreasing. If it wasn't for me, Vlad and some others, this community would be certainly dead already...

Does this mean that:

- MDSD practitioners are not very communicative?
- MDSD practitioners are too busy?
- MDSD practitioners are secretive about their work, and are only willing to listen, but not to speak?

- MDSD is a dying subject?
- MDSD is too complex to be grasped by the majority?
- MDSD is not seen as "the way"?

- This is a secondary community and there another, primary community?
- The community's service base (Ning) is cumbersome?

I'm confused and disappointed with the lack of activity here.
