I've noticed a disturbing (to me, at least) trend lately in a lot of answers on the main site. They're shouting. A lot.
We have this wonderful ability to add emphasis to things that need to be emphasized. But when more than forty percent of the text, or some part of every single sentence, in an answer is in bold text, it's no longer emphasis, it's annoying. (Or maybe self-aggrandizing; I'll leave the psychology of the motivation for the use of the double asterisks for another day.)
If you have key points to make, make 'em. But, frankly, the whole answer isn't a key point, ever. And shouting louder than the other guy (or gal) doesn't make your answer right, it just leaves you hoarse the next morning.
That is all. Thank-you.
