A new trade group has been formed, it is named the Web Analytics Association. I asked Ammon Johns if he had any direct influence with this trade group and he said no, but I find his recent campaign with the issues with referral tracking to be awfully close to the time this organization was set up.
If your interested in joining, it costs just $129 for one year, more information at http://www.webanalyticsassociation.org/en/cms/?54.
