This might not be possible (the info might not be in the API), but there's times where I'd like to see who is watching a cache - especialy my own. Is it possible to implement something to do this?
On a related note, is it possible to add a 'Top Watched Caches' page, so that caches can be sorted by amount of people watching them? I often find that interesting caches get a lot of watchers, but at the moment I don't think it's possible to identify those.
