WordPress profile badges.
On July 3, Timi Wahalahti opened a discussion on the Community WordPress blog on whether WordCamp volunteers, WordCamp attendees, or Meetup attendees should be awarded a WordPress.org profile badge. The discussion stemmed from a nearly two-year-old Meta ticket that was recently resurfaced.
The general consensus from the comments on the post seems to be that volunteers should receive badges because they are making direct contributions to the community. Most argue that merely attending an event is not badge-worthy.
