I was thinking about this the other day after seeing yet another poster on WP trash talking the PPR forum there and talking about what a cesspit full of awful people it is. I think of PPR as comparatively mild, I mean it's a bit rougher than the rest of WP, but is certainly tamer than most political forums on the internet at large. Apparently that's still too rowdy for some people so they avoid that board, natural selection having weeded them out from participating on that forum. Some people just can't stand to have their ideas attacked or questioned, or can't separate themselves enough from their opinions to discuss them rationally, or just don't like the confrontational tone there.
I2 seems to have a similar dynamic in that it's just too rough for some people, while others thrive in the less constrained environment. It seems to weed out a different kind of person, people who take themselves too seriously or can't laugh at themselves from time to time, as well as the sensitive in general. I also think it has a blindspot though, in that not having the usual mods and rules that AS boards tend to makes it harder for regulars here to function on a more moderated board. This is what I was trying to get at in my other thread, until I let myself get sidetracked by other issues and drawn into some drama; being rusty at posting here and all.
What I'm talking about is the reverse natural selection concerning people who never learn to post with subtlety and discretion because they've never had to, they never break bad habits because they never get called on them. This isn't a criticism, just an observation I've made over years of posting at different forums with different rules and noticing patterns. Not being allowed to just directly personally attack someone does have value in that it makes you think harder about how to come at them, how to use them as a springboard for an argument to the crowd, and how to actually persuade rather than bludgeon with logic. I think that sort of ability is a useful one to have in everyday life, since it's not usually a good idea to verbally abuse someone to their face, and learning to be persuasive rather than trying to win an argument is invaluable for an Aspie.
Again, just my thoughts and observations.
