For all the fulminating against dialogue tags other than said and use of adverbs after it, I've never seen a book that didn't do that some of the time. I think the key is to limit use of these words and not use them in silly or unnecessary ways ("he ejaculated," "she said explanatorily").

I agree! (Dare I add, "emphatically?") This little screed is about the tyranny of "rules", particularly in listicle format :)
