I noticed myself and others have begun receiving the enthusiast badge on superuser. As best I can tell, superuser launched on July 15 (see also question 1). That puts the launch 29 days ago (considering today August 13, which it is in UTC); which means no one could receive the badge yet. Additionally, this supported by a quick click through to the profiles of many of the users' who have received this badge, which shows them as having accounts for 28 days (which I assume will be 29 when the cache updates for today). Is this a bug, or am I missing something?
It's inclusive - there are 30 days between July 15th and August 13th.
I can post the data we have for your SU user account, but I'm seeing 30 entries, including the 15th and the 13th.
Discussion on gaming badges has often popped up.
Looks like in this case...

The badge as gamed you.
Hmm, you're right. I got my Enthusiast badge earlier today but I just assumed that it had been 30 days since it went live. In response to Brad Gilbert, I looked at the site for about 2 seconds before I signed up for my account, so there are no cookie issues (if that's what you're getting at).
Maybe Jeff is modifying the Enthusiast badge to be a little nicer by allowing people to miss at most 2 days? This might make those going camping sleep a little easier...
