This isn't so much of a site feature request, but I couldn't find a more appropriate section...
A while back the "thanks" button you see at the bottom of every posts seemed to be working normally.
I don't think it fully works anymore - you can still click it, and the user will be notified, but it is no longer possible to publicly see who has thanked each post. (E.g "Steve likes this")
Or have I just completely lost my grey matter somewhere?
