Soon it is going to be all Developer Summit all the time in the GIS blogosphere. Is there anybody going who has also been to any of the previous MapServer or Open Source Geospatial meetings? A similiar expectation seems to be building, with a relatively small group of people looking forward to less marketing spiel and more insight into their favorite platform. I would like to hear how it goes from someone who has seen how we do this thing in the open source community.
