The Center for Responsible Nanotechnology blog points us to Wise-Nano.org, founded by CRN director Chris Phoenix. It's a Wiki "designed to support collaborative research on the implications of nanotechnology and how to deal with them. In the process, it will produce a body of work on the technology, risks and benefits, and policy." If you want to take part in the evolution in thinking about how to handle potentially-world-changing new technologies, this is an excellent place to start.
