I think the situation is alot less gloomy and alot more simpler then you state.

 

1. The number of people on the Teamspeak has exploded since you were last "active" on the teamspeak
2. People have come to the conclusion that they do not wish to communicate with certain people
3. Thus it is easier to sit in temp channels where people group up.
4. It's a fact that the amount of people in the temporary channels is in fact much larger then the amount of people that used to be in the discussion rooms.
5. An example is the regular activity in Auxillian/Palimuza/Argonia channels.
6. Community is not dying, it multiplied into different communities, and is thus catering to a larger audience by having more diverse communities.

 

All is good.
