My experience
The proposal states:
Some expert or educated layman wrote an article and it might have taken him or her days or weeks of painstaking work. Then someone else ... can completely change this article in a couple of minutes. Often the expert will protest ... and he might experience some disappointment: he might even leave.
This is certainly my experience. I spent a lot of time improving some articles that fell into my area of expertise. Others, who thought they were knowledgeable on these topics but were not, then marched in a screwed up the articles. I became so pissed off at seeing my work destroyed that I retired my username and left Wikipedia. (I eventually came back, but only as a WikiGnome.) The articles on which I worked so hard are still screwed up.
This proposal has identified a real problem; I hope people listen.
