Nah, procrastination seems to be common among everyone. At least I have met very few people who weren't procrastinators. What's interesting, there exist pre-crastinators. Procrastination can be actually smartly used for your benefit, which is explained in another brilliant TED talk https://www.youtube.com/watch?v=fxbCHn6gE3U
Also I said quite clearly "I didn't refresh the page, I just had it opened in a separate tab when I saw and responded to your post." so I have no idea where you got the idea that it wasn't refreshing real time.
I was wondering if when I edit my messages in ShoutBox, then it will be noticed by people who don't refresh the page. I edit them more often than I would like, because I usually notice some mistakes in my English that I want to fix.
