Marco-
during a Wikipedia meeting in the city of Hannover we discussed about review systems for Wikipedia and similar things. Someone asked if it would be possible to show on each article page how many users have this article on their watchlist.
In a simple implementation, one might just retrieve a list of 100 unwatched articles. Then it should be fairly easy for regular Wikipedians to gradually distribute our current set of 300K pages among, say, 1000 people to make sure that every page is watched by someone.
Unfortunately, on the English Wikipedia that would include the 30K Rambot entries. One of the many reasons I think that bot-created entries are a bad idea is that people don't feel a connection to them, and hence no responsibility to make sure that they're in a good state.
Regards,
Erik
