I personally attribute this to the growing speed of Life. It's very rare for people to take the time to read a thread twice before posting, then think, then read over their own post before they respond. Much of the time, you feel strongly about something you read, and so you post out really fast to get your opinion out there. With the growth of what I've begun to call the "Right now, Right Here" age, when technology brings everything fast and how we want it, people have a tendency to respond on impulse.

So in short, I think that the issue of a lot of negative responses and ideas could be eliminated by everyone taking a step back, putting on some nice relaxing reggae or something, and slowing down the pace for a bit. By rushing to your response, you have a tendency to respond on gut reaction. True thought and progress comes best when you slow down and take your time, and fully think things through before posting and responding.
