At our "Making it Happen" table, we discussed how we could use tagging to help make social change, not just organize our own work.  We decided that we should come up with a few tags for the nonprofit sector and start getting them out there by recruiting "Tagvocates" who vow to: 

1. Use the tags all over the place
2. Recruit other tagvocates for their tag(s)

The plan is to get a set of tags out there, the aggregate the content (maybe with Suprglu?), and then foster a discussion about how we can use the content that we're tagging for social change.  For example - can a legal services organization use a set of tags to help aggregate content about Seattle area housing for their clients and agreggate it on their site?  Can an enviro group use a tag to aggregate info about a local developer to expose ant-environmental practices?
