The final speaker in this session at AoIR 2009 is Zack Hayat, whose interest is in active participation on Wikipedia. Wikipedia is a space for collaborative content creation as well as for interpersonal interaction (for example through its community portals - or whatever they are positioned as in the various international Wikipedia versions - and discussion pages). There has been exponential growth in Wikipedia participants over the past years, but the number of regular editors has remained relative stable; growth has been mainly in less active editors. Some 60% of Wikipedia has been created by 5% of its users, as Jimmy Wales has said.
