Recently (a few minutes ago), I noticed that on SO, all but one of the recently awarded badges on the list on the home page were Enthusiast badges. Normally, there are just a few at a time. Was this some sort of huge coincidence, or was this some sort of recalculation? If it was a recalculation, how often do these occur?
I know this is a strange question, but this seemed way too strange to be a coincidence...
