There is a countervailing trend away from privacy and secrecy and toward openness and transparency, both in the corporate and government sectors. And on the web, we have had several major steps forward in social tools that suggest at least the outlines of a complement, or opposite, to privacy and secrecy: publicy.
The idea of publicy is no more than this: rather than concealing things, and limiting access to those explicitly invited, tools based on publicy default to things being open and with open access.
Tumblr is a tool based on publicy. So is Twitter. Tumblr blogs and Twitter accounts default to open unless the user takes great efforts, and as a result the resulting communities are based on sharing of posts rather than membership in closed groups.
