I'm not sure about you, but 90% of the threads that I start to reply in, I stop midway. This just occured five seconds ago to myself once again. I read what I had written and I nearly said aloud "This is pointless garbage."
Now you may think everything I post is pointless garbage, and more power to you, but I often delete things simply because I don't think that the .000002 seconds it takes me to post it was actually worth server time.
This raises the question: Would the lounge suck ass less if everyone just hit Apple+A and delete a little more often?
