it's just a saying for old photojournalists meaning that content and composition will always triumph over technical details. it was also coined before the days of in-camera metering. actually, most photographer organizations today will not accredit you as a professional if you often do that.

you bought a dslr to be creative and have more control over aperture and shutter and not because you want to run around with your aperture set to f/8 to try to get the "sharpest" looking pictures. you can already do that with all point-and shoots because their depth of field are so large it will make any picture look sharper than even a dslr.

quantitatively, f/8 can make you run you into other problems with sharpness as your shutter speed will be too low and iso too high for most situations.

don't be afraid on using the largest aperture. if you're not going to print larger than 8" x 10", or post a picture online larger than 1500px on its largest side, sharpness will not matter for much.

Usually the sweet spot of a lens is about 1-2stops down from its fastest aperture (in most cases) however, it really is dependent on what you're shooting.

for my 17-40 f/5.6 is a lot sharper than f/4.0 and when shooting landscapes f/8 is my sweetspot.

The only times I make the effort to stop way down is with product photos in a lightbox, and with landscapes on a tripod. Other than these situations I find shutter speed to be of more value.

Yes any lens will have a sweet spot that its sharpest at but it also depends on the camera body itself. High end lenses are great and all but from my experience they also point out the shortcomings of dslr sensors.

I havent seen it mentioned yet but lens diffraction is something photographers should be aware of as well.
