Google has decided to discontinue Google Pages and has started migrating users over to Google Sites. As a result of this (and some of my own messing around with the site design) most of the code snippets I have on this blog no longer display properly. I've updated my post on syntax highlighting in blog posts to warn people away from trying to use the approach I've described there, and which is the one I had be using for code on this blog.
I plan to address the problem soon enough -- when my schedule allows, that is.
I guess this is a good argument for hosting my blog on it's own server (which I've been considering), which would have obviated the need for the Google Pages approach.
Oh well...live and learn.
