The 'wiki' form of collaborative web site, emerging dramatically with the great Wikipedia as its lead example, has to be my favorite cultural technology development of recent years.
Wikipedia is more just an amazing collectively-created web site. It also the headliner for a huge new phenomenon in collective creativity. More than 9000 wikis hve been launched using MediaWiki, the same free, open-source software that runs Wikipedia (and that's just one of the options for wiki software).
