I think the better point to be learned here is administrating any public facing server has to be more than a hobby. The barrier of entry to installing WordPress or PHPBB is extremely low. Anyone can do it. Only a small subset of those people will ever take the time to understand security issues and keep their servers patched. I mostly blame the "I read a 2 page HOWTO now I'm an expert!" types. Pay someone to take care of the details if you don't want to handle it yourself. I've previously used Blogger (recently switched to SquareSpace) for exactly this reason. I don't want to spend my free time installing patches and checking logs. (I do enough of that at work)
