Perhaps I'm the only one who finds this a little concerning in my part, but lately I've been feeling that too many users are trying to watch too much of Wikipedia at one time.
Let me elaborate a little. It isn't uncommon for the normally active user to have hundreds, if not thousands, of pages on their watchlist. Then, when somebody makes an edit that a certain user doesn't agree with, it gets changed or outright reverted. It's like, at the least, a form of a bunch of "Big Brothers" looking over an article and, at the worst, an outright form of page ownership.
I've been on the low end on watchlisting pages myself, but a couple of months ago I decided to "unload" my watchlist, removing most articles that I have extensively worked on since I came onboard -- going from about 50 pages watched to about fewer than 10 pages watched, only keeping those I'm monitoring in the short-term.
Personally, I found unloading my watchlist liberating, and I would hope that more would do the same. There's always that steady stream of vandal-fighters to stomp out any clear vandalism that pops up. It's hard to explain, but I think it's a good exercise in assuming good faith that others will make constructive edits in efforts to improve pages.
