An entirely too-long blurb yesterday morning on Weekend Edition was about a “rabbit hole” — the thing that happens when you get online and click from one thing to the next.      I’ve had some awesome opportunities come up from going down rabbit holes… but they’ve reached a critical mass where I need to […]
