Currently my plan is to assume that anyone who has edited an article in the past 6 months has it on their watchlist. Obviously a very corse assumption.
I don't think that most people add most articles they edit to their watchlist. I don't (my watchlist has about 3k and I've edited ~30k distinct articles, IIRC).
I'd assume that people who watchlist the article are, usually: * their creator * editors who contributed to it extensively * editors who discussed it on talk * editors who have made 1+ revert on it That said, I'll stress again that neither of those is certain.
