A couple more hours of hacking, and the templates are all new, and more functional then ever.
I am making heavy use of Yahoo's UI library, which makes lots of things much simpler:
Layout using Yahoo Grids
I spent hours making the layout you see now, and the one with Grids works better and was done in minutes. Avoid reinventing the wheel works for webpages, too.
Calendar using Yahoo Calendar
Styling using their reset.css stylesheet.
That stylesheet removes all styling from your page. That way, if there's something there, you put it.
I used that, added a slightly simplified stylesheet based on Firefox's default, Restructured Text's and Silvercity's, and all the customizing I needed to do to achieve a simple but functional layout were 30 lines of CSS, compared to the rather monstrous pyds.css my blog currently uses.
I turned all Technorati/HaloScan/FeedBurner/Talkr thingies into macros that take as configuration your personal data (for example, HaloScan ID) and if necessary a post.
If the styling was a little more done and a few bugs were ironed, I may even start uploading the site using bartleblog instead of PyDS soon :-)
