It's all good together, I think -- makes for more interesting reading when what you're reading about isn't just the same note over and over again. I'm guessing readers aren't returning just because you talk about Korea, but because it's you specifically talking about Korea and whatever else you choose to talk about.

I'm one to talk, of course, having such a schizophrenic blog. If I cut out all the non-cranky (i.e. non-political) stuff, I'd probably be as boring as all the pure warbloggers are -- to the people who already read, and to myself!
