You all are right, trails are blazed more extensively in the east, but often with good reason. How extensively to blaze a trail is a tough tradeoff between unobtrusiveness and safety, and the obvious LNT benefits of keeping people on the maintained trail.
In defense of Mount Monadnock's blazing scheme: although it is not the highest peak in NH, it is the most hiked mountain in the Western Hemisphere -- something like 125,000 people hike it a year, mostly in the summer. On a summer or fall weekend expect over a thousand people to summit EACH DAY. Many of these folks, as you would imagine, are not experienced hikers -- lots of Boston suburbanites. The trails are extensively and clearly blazed in order to allow non-wilderness types to safely enjoy a mountain experience and appreciate the wilderness. Blazes are a better alternative than a road, for sure! Those looking for a more pristine wilderness experience go north to the White Mts, which are also blazed, but less aggressively. Use of cairns is more common there particularly above treeline. I've always thought the line of cairns with white quartz tops marching off into the distance across the Presidentials was beautiful......functional too, particularly in the frequent whiteout conditions.

I'm in violent agreement with everybody's point that on a trail like Skyline, flourescent paint is never appropriate. I don't know if I was oblivious, or if it was done very recently, but I didn't see any of it last Wednesday when I hiked Skyline. Just the white dots and numbered switchbacks on the lower part of the trail from Ramon Rd.
Good luck to all of you doing God's work eliminating these obnoxious markings......
