I'm building yet another blogging platform (not quite) right now. It isn't going to be Wordpress, but it will be managed and won't cost you $200/mo. A carcycle, if you will.
To carry the analogy to its end: you seem to be only using the car to drive ten blocks to work. In other words, you only serve static content + comments. Which is why I'm curious what, specifically, compels you to stick with Wordpress even though there is an obvious cost (be it money or effort.)
