Oddly enough, I feel like this problem has actually gotten a LOT better on this forum over time. ^^; When I first got here, people would regularly just read whatever title you wrote and immediately try to respond to the thread without paying attention to any details in the OP...and then accuse you of being manipulative when they ended up misunderstanding what the thread was for. Fun times~
Fortunately, that doesn't happen so much anymore...although even if it did, I'm kind of over it. =P I've had so many "discussions" with people who can't even be bothered to pay attention to what they're saying to you, let alone what you're saying to them, it's become part of my baseline expectations when interacting online.
