The formation of CMPros was just announced. It is a professional society for content management professionals. From the home page:

A group of thirty content management experts from around the world has announced the formation of CM Professionals, an international community of content management professionals whose purpose is to further best practices based on shared experiences of experts and peers.

A lot of organizing seems to be going on in the web professions, which is a stage of growth for any new field. If they follow the pattern in other industries, there will be a lot of new organizations over the next few years which will eventually consolidate into just a few dominant associations. It will be interesting to watch from an association management perspective.
