Interesting how most didn't pay attention early on (the meetings obviously so mind-numbingly boring) but as they started "waking up" or stopped suppressing their thoughts they did start paying attention.
That was my case as well, I started actually listening and realizing what was being said. The public talks ceased being "public" and became directed at JW's. The TMS was mostly useless. The Service meeting was either a sales seminar or a guilt trip about not doing enough, no matter what was going on in your personal life.
Like Undercover said so well, when a scripture was read, I would read the context around it. Most of the time the "point" being made didn't jibe. Especially the use of isolated verses in the Hebrew bible to apply to whatever the point they were trying to make was.
