One reason I find list of recent badges interesting is that it shows achievements by users of particular sites. This might help me to notice some interesting posts or some remarkable thing a particular user was able to do.
The gold badges seem to be the most interesting from this viewpoint. (Admittedly, there are even gold badges which are easy to obtain, such as fanatic badge. But, in general, it is more difficult to get a golden badge than silver or bronze one.)
Feature request: Could we have on the badges page in the view for gold/silver/bronze badges the list of recently awarded gold/silver/bronze badges (instead of the list of all recent badges, which is shown there now)?
