Doesnt bug me in a bad way, it is just interesting.
It may be like colloquial nomenclature or something. dumplings vs pot stickers for example.
A horse by any other name......
I like omelets too. But I really like fritattas. Especially when we have a family get togethers down the shore. We usually make a giant frittata with asparagus, potatoes, buttery homemade croutons, scallops, shrimp topped with sliced ripe fresh jersey beef steaks and cheese. Some blistering strong coffee and you have a Capozzoli's summer time hangin on the beach all day breakfast.
It would just be to much of a PITA to make seafood omelets for everyone.
