One unanticipated value of blogging

Over at Snarkmarket, I ran across this thought today:

I always tell people that blogging is useful, even if nobody’s reading, because it forces you to have an opinion on things. You don’t realize how blankly you experience most of the stuff you read every day until you force yourself to say something—even something very simple—about it.

When I was job hunting earlier this year, I benefited greatly from this blog: I had given more thought to many of the issues that came up in interviews than the last time I was interviewing before I started this blog.
