Who has time to blog?

I think of some of the insightful blogs I've read, or the politically charged ones, or the whistle-blower style blogs. I barely have time to read them, let alone write something equally worthwhile. I have no idea how anyone has the time! I would love to write the kind of blog that people turn to for the latest uproar in the world. But for now I'll have to be content with finding the time to even scratch out a handful of meager words here and there.
