Hm, this thread is very interesting to me. I regularly play on the top 3 difficulties and as a rule NEVER build scouts. I do not find them to be very critical to my game play but I tend to either turtle on smaller landmasses and go for cultural/diplomatic or use mounted unit rushes when I have several Civs around me. Granted they may be useful for the latter strategy to find stretches of plains/grassland to move on, my first victims are usually close enough that this isn't a big deal.
I do explore with a trireme as early as possible however, I find you meet more CS first this way and end up getting more gold than you would finding a gold goodie hut. On that note I usually can grab a couple goodie huts anyways with my warrior before heading back for defense, if it can find an extra hut or two I could see a scout being a real asset early in the game. If they don't find anything extra though it would feel like a big waste to me. I will have to explore them as a flanking unit to perhaps get over that feeling.
I'm going to try building some on my next couple games right away and see if it feels like it improves my early game. I could see the happiness boost from finding more NWs being very beneficial as I frequently tend to run into happiness problems, in games which I don't found a religion, around the early medieval era.
