I don't know if I can say exactly... it's just something that is picked up over time. I don't think I'm alone here.
You learn what the atmosphere is... this isn't limited only to the internet and forums, but in many things in life.
Kinda like walking into a buisness.... dealerships, etc... some are laid back, some you are uncomfortable... some in between. You might not be able ot explain in words.. you just know. Ask me what I think of a dealer in their showroom, and then ask me after we leave and you might get different answers.
It's human nature.
Like I said, my memory isn't that good, but I know there are things that have been done and said over time that create a "feeling". And there are those who have voiced their experiences in other forums, right or wrong... about some post that got edited, etc. I can't recall a single specific example, but I have read many.
This may be the best forum or it may simply be the most pouplar... can't argue that. But I can say it's weird to see certain issues discussed in other fourms and I'm thinking to myself : "wow, they are actually saying that here? isn't that going to get edited or something? " and it's cool that it isn't cutoff, locked, edited, deleted, and noone is banned.
