Anyone had experience using US oak acorns for food?

My home in New Orleans is partly shaded by a Southern Live Oak (Quercus virginiana) and this is a year it's been producing a prodigious crop of acorns covering the yard.

Pages on a quick websearch say "Look for fully mature, brown acorns with the caps still attached." Well, from many hundreds of acorns on the ground around the tree I found only one with the cap still attached. Does this mean the rest are bad?
