[Artful Writer](http://artfulwriter.com) has a great list of [shorthand jargon](http://artfulwriter.com/archives/2005/04/test_ms_html.html) from the Zucker-Abrahams-Zucker school of comedy. Even if you never end up using the terms, they provide a useful guide to the do’s and don’t-do’s of comedy writing.

It sounds like you, Hugh, are geeky enough that either [WordPress](http://wordpress.org) or [Movable Type](http://movabletype.org) will work fine for you. WordPress is done in PHP, while Movable Type is (mostly) Perl, so if one of those languages is more your strong suit, let that be your guide. And if you don’t feel like climbing under the hood, the default installs of either WordPress or Movable are pretty powerful, and both have plug-ins that let you do a lot without touching a line of code.
