David Brooks, in his Times column today (emphasis added):
When I started covering presidential primaries, the best part was getting to know the candidates. We journalists would ride around in vans and buses with them and get an intimate look at what it’s like to endure this soul-destroying process. But the ubiquity of Web cams and tweets has ended that off-the-record culture. As the technology gets more open, the lines of political communications become more closed.
True enough, and I'm surprised that more people don't consider this paradox.
