Some wiki-based communities give their users an award called a "barnstar", as a continuation of the "barn raising" metaphor. The concept of the barnstar as a was created by SunirShah on MeatballWiki. Web designers were invited to incorporate a similar barnstar design into their project as Easter eggs.[1] Wiki barnstars were introduced to the English Wikipedia in December 2003 and Commons in February of 2008 (officially). Since then, the concept has become ingrained into the culture. They are a form of warm fuzzy; they are free to give and they bring joy to the recipient.
