"Writing reveals holes in your thinking. When your ideas are written and looking back at you, they're a lot less convincing than when they're just in your head. Writing forces you to mature your ideas by thinking through counterarguments."
Totally agree.
I'd also add that writing publicly (blogging) forces you to evaluate and really consider your true convictions with regard to whatever it is you're writing. Because you're going on the record with something - for all to see. And there's bound to be people out there that disagree with you. If and when they come, will you still be proud of and confident in what you wrote? If not, reconsider your stands.
