Thx kb. I'm not committed to comic anything. I just want a good clear readable font -- not for the blog particularly, but for all my course material. Of course there are other considerations besides font - there's spacing between lines and between letters. I'll pop the question over on askhubski. Some people may be irritated by the signage/clippy/childish attitude suggested by comic. My students have been mocking me for a while for using it. Since I'm creating new curriculum right now, I can change the whole book to something less irritation-provoking.
I'm limited to the font selection on my computer. When I download new (free) ones, they come with embedded stuff that screwed up some other functionalities.
I used to use a combination of Bank Gothic and Bell Gothic, and then Battlestar Galactica came out and Bank Gothic took over the universe. I tried futura for a while but it's not particularly legible; I tend to use Anonymous Pro for most things these days.
