One thing to bear in mind -- there is a difference between on-the-fly handheld shooting, like Tim mentions, and in which "acceptable sharpness" has a broader interpretation. and "critical demand" shooting in which you want to take strides to optimzize that critical sharpness in your technique. Not that we should ever be sloppy, and I still tend not
to center-point focus and recompose, but I can't afford to be too
picky when I'm shooting something on-the-run.
This is a good point. As an example, I shot some roller derby a few weeks ago, and for the majority of the time I was using center-point AF and AI Servo to focus the moving skaters. But in the brief times when the skaters were NOT moving, I would focus and recompose to get portrait-style photos, or full-length body shots. I didn't have time to switch AF points and focusing modes before they were rolling again. I suppose I could have switched the lens to manual focus and back again, but I'm not that good yet.
In more controlled situations - posed portraits or still life - then it's better to choose the most appropriate AF point, or if possible use manual focus. As alluded to above, in many situations when you focus-and-recompose, after you recompose your focal plane may be behind your original target. There's a thread around here somewhere that talks about it in depth, and gives diagrams to explain it better.
On a side note, in controlled situations, I love LiveView + 10x Zoom for manual focusing.

Now I don’t use autofocus so I can compose where ever I want in the frame and still get good focus. I just shot a wedding with manual focus the whole time and there are much better pictures because I was not held down by the focus points.
How long did it take you to get confident and comfortable enough with your skills to pull this off? Any tips for a manual-focus amateur? (I guess we're getting off topic here.)
