Interesting comment. PR may see social media as a threat, for exactly the reason you've mentioned. "Well-informed" is relative I think to what you're doing.

Interesting comment. PR may see social media as a threat, for exactly the reason you've mentioned. "Well-informed" is relative I think to what you're doing. For example, someone doing hard science research in a lab may only need access to scientific journals. She needs to keep pace with what is published in her area of research only; she could be oblivious to what's happening in the world and still be effective in her job. But from what I know of Buffet, I think he needs access to what journalists are saying. Again, it matter what you're trying to do.
