Perhaps some members of the Digital Bridges community will be interested in the new, monthly "Web Analytics Wednesday" get together sponsored by the Google Analytics consultancy EpikOne. They are held in the back room of Halvorson's in Burlington. The next one isn't scheduled yet but will probably be mid May - - you can check http://www.webanalyticsdemystified.com/wednesday/ closer to the event.

Or, if you join the Google Group "Burlington Interactive Group" you'll receive an update: http://groups.google.com/group/burlingtoninteractivegroup

The idea is an informal forum on web metrics best practices etc., but it is unstructured and wanders casually across many online marketing and tech topics.
