I loved the sense of people thinking freely in the beginning, but increasingly the place was being filled with propaganda by minds that hated and wanted to distort reality. There was a sense of community, but it was aggressive, rather than encouraging, and almost all from a single point of view. And finally there was a sense of entitlement to acquisition that really grated - the idea that if something was digital then it MUST be free (both as in thought and beer) and that they had a right to copy and acquire it gratis.
I'm also back to wondering about shutting down Facebook (and would have done so already if I didn't find it so useful to connect with some people).
