Blogging forces you to write down your arguments and assumptions. This is the single biggest reason to do it, and I think it alone makes it worth it. You have a lot of opinions. I’m sure some of them you hold strongly. Pick one and write it up in a post—I’m sure your opinion will change somewhat, or at least become more nuanced. When you move from your head to “paper,” a lot of the hand-waveyness goes away and you are left to really defend your position to yourself.
