On the tools side in particular he Shirky says:

“There is no such thing as a generically good tool; there are only tools good for particular jobs [but]when you improve the available tools, you expand the number of plausible promises in the world.”

and

“new tools are not always better. New tools, in fact, start with a huge social disadvantage, which is that most people don’t use them, and whenever you have a limited pool from which potential members can be drawn, you limit the social effects.”
