I have at least twenty years of experience of Wikipedia, and it is exactly how it works much of the time. I lost count of the occasions when people with no knowledge of a particular subject kept trying to delete articles on it. Then there were the continuously changing rules, jargon and oligarchical structures...

Some subject areas have much better coverage than others: linguistics is much better dealt with than sport for example.

Nowadays I rarely edit Wikipedia, because they block most shared IPs. I used a named account for at least ten years and it was counterproductive.
