I agree completely with your statement.
May I add that there is also the aspect of when someone has joined this forum. It's like any community that you move to. You buy a place in a small town because it was a quiet, sleepy town. However, as more people move in, and the way of life becomes more diverse, the newcomers may not know the way it used to be, and try and the community to something they want it to be. Sort of like what happens when people move to a farming community from the big city. They move because of the quite, but they don't like the smell of the farm animals, so when they have enough ex-city dwellers, they ban the farm animals.
When I first came upon this forum, Sony was new to the DSLR business, and many of the members here were refugees of the demise of Minolta, and all of us were pretty much in the same boat, hoping that Sony would succeed and allow us to continue using our legacy lenses.
As time has gone by, there have been new people coming aboard that don't even know that Sony's A-mount was developed by Minolta. People that frequently posted have drifted away for whatever reason. Some of the posters have become the 'bullies' of the forum, trying to chase away those that they don't agree with. And some have found a home here and can float with the punches and changes.
Like it or not, this forum is like that quiet farming community that is being over run by the city dwellers.
