If you click on the "Comments" button, every time you refresh, you'll get the latest comment that's been posted regardless of the thread.
So somebody who simply wants a particular thread to get more attention will type in BTTT or Bump so the thread shows up at the top of the page.
It's a way to prolong a thread life.

Just making sure I understand the reason behind doing the Bump or BTTT. I'm a little slow on the uptake at these things. :-)
Thanks again.
