Before publishing the previous post, I looked into recommendations for syntax highlighting in coding-oriented blogs. In a quick search, syntaxhighlighter showed up repeatedly as the preferred choice, so that's what I went with.
It looks like I'm not the only one that isn't entirely happy with that solution (although by using the "pre" tags rather than "script", my code should at least appear in the RSS feed).
Working with ReST would certainly be easier than the semi-HTML I'm currently using. Still, I think I have plenty to learn about Blogger's formatting tools before I abandon them entirely in favour of preformatted posts (which have their own drawbacks).
