" third key aspect of Wikipedia’s good gameness: it has good game community. Good game community requires two things: plenty of positive social interaction and a meaningful context for collective effort. Wikipedia has both. As Wikipedians describe it: Every unique location (article) in the game world (encyclopedia) has a tavern (“talk page,” or discussion forum) where players have the opportunity to interact with any other player in real time. Players often become friends with other players, and some have even arranged to meet in real life (“meetups,” or face-to-face social gatherings for frequent Wikipedia contributors). "
