Close to 600 attendees!  My Flickr set from the MinneAnalytics Forum on May 21 is here: http://www.flickr.com/photos/graemethickins/sets/72157629845302404/

(For more on the event, search on the Twitter hashtag #bigdataMN — it was active!  Also see the Eventbrite page, which has a list of the attendees and also now contains links to videos of some of the speakers' presentations.)
