Just realized we can "appreciate" "IP" addresses. I'm not entirely sure they'll receive anything but if they do this seems like a a pretty bad idea. One never knows who really did something. At best it is a guess with usernames, it is far worse with IP addresses  because the person who might receive the appreciation might be completely different from the person who actually did the work. Think of a netcafe, a shared internet, or even mobile devices that change their ip quite often.

In fact, it may be downright confusing to suddenly get a message after going into a wiki for something you didn't do especially if it is the first time you're on a wiki.

It might also be a good idea to delay the appreciation for a few seconds or minutes, and add an "undo appreciation button" that cancels it out. Someone might click wrong link and appreciate vandalism...
