You seem to be forgetting that for the community to transition to Harmattan, the members of the community needs an N9(50). But most of us do not have one. This is partly due to the price and partly because many have migrated to other platforms (android) disgusted with Nokia.

Also if I remember correctly, for the N900, lots of devices were distributed to developers at various conferences. This is not really the case for the N9. EDIT: It seems I am mistaken. See pycage's post below

All you can do is hope that slowly over time an enthusiastic community forms around your beloved N9. No use calling this community "old men clinging to their last strands of hair".
