Tony, you signed off your post with an ancient Chinese curse.
On the subject of organs, I believe that the church organ is all but dead. The instrument's sheer difficulty to master, coupled with the extremely low return on one's investment of time and money learning it (I had to fund all my lessons, music, organ shoes, and examinations with NO help from the church) and poor/zero pay as an organist is hardly an attractive prospect to a young musician. Pipe organs will gradually migrate from churches into private ownership or into skips because A) there will be no-one to play them, and B) because the culture has changed.
On the subject of internet fora, I believe that people have a much shorter attention span these days, and, dare I say it, the average person's intelligence is quite poor and getting worse. People prefer posting short messages on Twitter and Facebook rather than the more thought-out letter style response of a forum post. Though occasionally, you do find some intelligence out there:
"It is currently 10:29PM and I am watching the decline of Western civilisation on television" (Twitter poster's response to Channel Four's odious Sex Box programme)
