Well, even given the possible duplicity mentioned by SJD, I didn't see that thread, and I want to respond to Gerry... 
I've recently made changes in my game, didn't really focus on my grip too much but I did notice something similar. I was looking for checkpoints to make sure everything felt straight, looking at my wrist position (in/out, forward/back), knuckles, etc.
I've been sort of channeling Darren Appleton lately, and found that I was holding the cue looser like him. However, as soon as I got the cue up more in the webbing of my hand, between the thumb and forefinger, everything got even better. I wasn't gripping any tighter per se, just had a more secure grip around the cue. For me I guess, having that looseness or space seemed to cause some issues, or perhaps caused my wrist to function differently. As soon as I cinched it up a bit - same angle, motion - everything just tracks in a perfectly straight line.
So I think the grip can be very individual, but in general striving for a neutral and relaxed grip, with constant pressure more or less through the entire stroke, should be the goal. I think the key is to find what works, and then analyze it so you have checkpoints to "find" it again if you lose the feeling or take some time off.
