It's the premise that exposing ourselves to communities based on idea dissemination (HN, Twitter, etc) maximizes our serendipity. Reading X article may set you on a path that leads to an opportunity you never could have predicted.<p>As with all things, moderation is critical. On one extreme, you're just gorging articles and reading about ideas. But you don't do anything about them, you just keep on reading. On the other extreme, you shut out the world and live in your head. There is the chance that you'll "create your own opportunity" (to use the phrase of the author) but you limit your chances by not interacting with others.<p>Read something, see if you can act on it. If not, move along. There's no reason to take either extreme.
