In the late 1990's, I was taking some graphics (Photoshop, Illustrator etc.)and I had a teacher tell me that I should back everything up and do a clean install about once a year.

So, you are saying back then, it was okay but not a good thing on OS X?

Correct.

The overkill of reformatting instead of just re-loading aside, the real point of doing that was to defragment the files on the disk. In the classic Mac OS, this would give a pretty good performance boost, especially if you used apps like Photoshop and processed lots of mid sized files.

A number of improvements have been made to the HFS file system since then, to reduce fragmentation and fix the performance issue. Plus, OS X watches things and does critical defragging automatically, as you use the machine.
