I didn't know about milk in the eggs until about a year ago when I saw my aunt do it. Now, I cannot eat scrambled eggs unless they have been prepared with milk!
The secret to purist fluffy scrambled though's, to keep scraping the pan, "scrambling" the eggs and taking it off heat just when it starts to look half-done. Taking it off heat just when it looks done makes you end up with gummy scrambleds :^__^:
I never knew that adding milk made the eggs fluffier..I do know that adding a tad of milk in eggs you microwave helps keep them from turning green;)
