Of course, the nerd in me had to go look around to find an answer about softened vs melted butter. Turns out, the science behind it is that warmer butter (melted) spreads more during baking, so you get a flatter cookie with a gooey middle and crunchy edges. You can offset that with more flour, or creaming your sugar and butter at room temp.
Browned butter cookies are another critter entirely though. So grain of salt.
