Brian,
It isn't a playground. It's a workplace, with a little playground in the mix. We do have some fun, but the forum is an essential part of our work, and that is its primary purpose.
Some people on the forum like to discuss some very esoteric subjects, and a few tend to become argumentative and even combative. The noise can make it hard to work.
Some feel, as you do, that the discussion gets cut off too soon, or that it should never be cut off, but I believe this forum would be a lot less welcoming to new users and would soon become the playground of a few.
If you feel the need, there are other forums where such discussions are more welcome. Private messages are also available.
Your contributions are much appreciated.
Jim
