I skimmed a web design book at Barnes & Noble today that said you should underline your links. Rather than slavishly follow that advice, I've simply underlined the links in blog entries and left the rest alone. (The entry links are the most important ones to pick out, since they're buried in text. Underlining every link would be ugly.)
I also am experimenting with an alternate stylesheet that produces a “run-in” look like that used on a lot of Blogger blogs. If you have Mozilla or the Phoenix alternate stylesheet switcher plugin (it may also work in Camino™), you can play with it. You can also choose the so-called “serif look,” which uses a Serif font (like this) for entries. Unfortunately, these styles don't persist between page visits in Moz or Phoenix, so the usefulness is pretty limited for now.
Finally, behind the scenes, the front page is now moved over to a pure mod_python implementation using the Publisher handler. The main advantage (beyond a further speedup in the page rendering and cleaner code — no more fiddling with the FieldStorage class) is that it can properly deal with If-Modified-Since headers again; real CGIs did it automatically, but mod_python's CGI emulation doesn't handle them right for some odd reason. Still slouching toward a code release; the next step is to convert all the other backend scripts.
