It's always gratifying when meetings and discussions turn into actions and forward progress (and it happens far less often than most of us would wish).
The just-announced Social Software Alliance is an excellent example of exactly that. This group grew out of of the "Emergent Democracy" discussions that Joi Ito started a back in February, and that have grown a bit in terms of scope and focus.
The idea is to start bringing together the people who are interested in and knowledgable about social software, to start developing standards and tools in a collaborative way. There's a lot of working at cross-purposes and duplication of effort right now, I think, and this may be one answer to how to create a community of developers and researchers.
