Even wikipedia recognizes the phenomenon of over grinding coffee
I'm not one to rant on something without providing some sort of way to look it up.

In short, the finer the grind, the quicker the brew should be. Espresso is super-fast and has a very fine grind. Drip coffee requires a slightly coarser grind otherwise you have increased acidity and bitterness. French press? Very coarse.

The best grinders are adjustable gravity feeds so that coffee at the perfect consistency is dropped out the bottom. The reason for multiple grinders at coffee shops? They use one grinder per roast used since each roast has a different grind setting at which the best balence of strength vs over-extraction (ie unpleasant flavors)occurs.
Thanks to everyone who feeds me coffee, I do appreciate. In return, enjoy the tasty benefits of science!
