In this post 9/11 world it is an extraordinary day that a ruling comes out in favor of an individuals privacy.  I'm not advocating anonymous Trolling of forums or wikis.  Quality forums are based on strong communities who should be given the technology and tools to police themselves.  If we find that website owners are responsible to give away the id (or IP) of any user whose posts anyone finds questionable the burden will be too great for forum owners.
