At the Smallworld Americas User Conference in Baltimore this year, a GE-hosted forum discussed how Smallworld could gain exposure in the big world. I would like to suggest that one way to do this is to provide sponsorship for these events and get staff/partners to provide presentations for these events. At the very least, send observers.
PS. If you are travelling from out of state/country, you can attend the two September 2011 events in Denver, then spend a week travelling around the Rocky Mountain west and then travel over to Chicago for the Americas User Conference (September 25-29, 2011). What a great month that is going to be!
