Sadly, a few of these articles have been edited to death since and some of the current versions bear little resemblance with my contributions. Readers now complain on talk pages again about issues that I fixed years ago. No matter how much work you put into a Wikipedia article, be prepared that your valuable contributions will have vanished within a year or two. Parts of Wikipedia feel more like a field that is ploughed over again and again each year, rather than something that continuously improves with time.
