</div>Well, none of the schemes proposed so far actually deal with the case<br>
of subtle vandalism. They're all assuming it's possible to determine<br>
whether an edit is good or not. The only fool proof way of doing that<br>
is to send someone to check it out in reality, which is going to be a<br>
fairly intractable problem. The obvious vandalism is the low hanging<br>
fruit, and the obvious place to start if you're aiming for a more<br>
stable map. I'd imagine people will do this for smaller areas in a<br>
similar fashion to how we handle the coastlines for the cyclemap (ie:<br>
we grab the data every so often, and just keep the old data if the new<br>
looks too broken in a critical place -- at that point I usually try<br>
and fix it of course).<br>
