I found a little forum on how to edit Wikipedia articles. People discuss ways in which they edit articles in Wikipedia. It shows us that many people search through wikipedia articles and fix things that they believe are wrong. But some people have found that once they edit the article the author just changes it back.
Some one states
” Any major changes i ever make (and in fields i actually know something about) invariably get edited back by someone else anyway, so ive pretty much given up on trying to add anything. The whole edit process has become way too bureaucratic. You can barely change a sentences syntax without spawning a page full of discussion. “
