Internet forums are strange places. One trend I've seen is how they tend to bring out the narcissism in many. Its a bit of winky-measuring, or establishing the alpha-dog of the group. Many jockeying to see who the most knowledgeable is on any given subject. This forum seems to have a little less of the manhood-measuring than many other forums I've been on, but I have noticed the same thing you have in that there's a lot of people just ignoring what others have posted...not sure exactly which psychological phenomenon that is...
This forum is unique, but it does have some of the usual internet forum characteristics.
What it doesn't have is a lot of bickering, foul language and name calling. Thanks to the mods for that.
What it does have, is a lot of people with skills, who are willing too share their knowledge with others.
It is a bit of a social watering hole, especially in free parking.
I think part of the phenomenon of not acknowledging others posts very much, is related to winky-measuring. Instead of adding on to someones post, making one of your own, even if it is an exact copy of what's already been said, gives you a flag you can plant. BTW, my winky IS the biggest!
Readers do need to appraise each posters expertise, since we would all like to think we know it all. And in the race to be "The expert", we may overstep our knowledge.
You have your lurkers, your post count whores, your know it all's, your really do know it all's, your funny men, your doom and gloomers, your self righteous and your kind and helpful people. We're not all keyboard commandos, living in our mom's basement.
So we have the usual mix of people. And the usual mix of posts and threads and conversations.
All in all, I like it. Do miss some of the old timers though.
