There's been some controversy about it... some well-known instructors advocate the pause on every shot. Almost nobody does it every time, but a few do it frequently. Niels Feijin uses it a lot - http://www.youtube.com/watch?feature=player_detailpage&v=kRPHnE8qnK0#t=127s
Some us do it to cinch a long shot, a thin cut, or on a shot where you must hit a pretty specific spot on the cue ball.
It does not have to be very long, half a second is fine, and sometimes a little up'n'down motion kind of disguises the fact that there's no forward or back motion. I think shane's stroke has a pause sort of hidden this way if you know to look for it. http://www.youtube.com/watch?feature=player_detailpage&v=4mzQzNNlXfU#t=1572s
I notice he had to stop and get up off his shot before shooting that ball, even though it looks straightforward... so maybe he also has more pause on the tricky shots and less on the gimmies.
BTW, I think the reason you don't see many pros using it is because the pause isn't something most players develop naturally, it's something that's taught... and a lot of pros seem to have developed their gift for pool early on, skipping right past formal instruction or only getting it long after they'd already developed a consistent stroke.
Personally I think it's the nuts and you definitely don't need to worry it's a bad part of your game or is holding you back.
