Wikis were the original breakthru apps for web-based collaboration. They used to be a pain to set up and run, requiring deep expertise in Perl, PHP, or both, originally. Now, however, you can get started wikiing in ten seconds or so, with features and options we early wiki adapters only dreamed of. Check it out for yourself with one of the slickest free wiki-farm sites on the web, PBWiki, at http://www.pbwiki.com
