Having spent well over a decade on this and several other online sports forums, my general rule of thumb is: if what someone posts gets me angry to the point of blocking people, turning into an Internet tough guy, losing sleep at night, etc. then I simply walk away from the keyboard, turn off the computer and leave the forum. Simple. If it isn't fun and entertaining and positive, then just leave.
I also agree with the above sentiment that, with the team being lousy for the better part of a decade, we simply run out of things to talk about other than "it's the GM", "it's the owner", "it's the players", "it's the culture", "it's the system", "it's drafting".... I get bored with that stuff, so I just don't post very often these days.
