I like the medals too! However, I would like to know what to expect. Or, in other words, know how to achieve receiving a particular badge.
I would like to be able to click on one of the badges that I don't yet have and see what it take to get it. For instance if there were a badge called "The Reporter" that takes five posts to "NEWS" and/or five posts to "Best of Sweden" then I would be able to see that and actively plan to achieve it.
