Achievements are supposed to encourage editing, but in my experience they mainly encourage trivial editing (aka points-gaming) for the purpose of racking up the badges, and in some cases even vandal editing. I have come across some wikis where they have been enabled, then disabled again a short time later.

For articles, talk pages are vastly preferable to message walls, as they allow replies to replies and swift deletion of spam comments instead of having to tediously pick them off one at at time.
