Viable alternatives for serious aviation discussion

Then Usenet is your best bet. Many people find it difficult to have
their input moderated. You are simply expressing a preference to which
you are entitled.

Most people tolerate moderation very poorly, but they love to see other people
with whom they disagree being silenced. Many people will choose a venue in
which they know that the allowed opinions match their own; that way anyone who
disagrees with them will be "moderated," and those who agree with them will be
left unmolested.

The problem is that many discussion venues stagnate, since nobody is willing
to discuss anything on which there might be a difference of opinion. The only
things people will discuss are the things about which they all agree already.
It gets pretty boring after a while.
