The two typefaces I have used in my header are Century Gothic for the Pigtown Design part. I like CG because it is clean and unfussy. The other part of my header is called Miss Brooks, but that's isn't the "latin name" for it and so you may have seen it called other things.
I go through phases when I like some fonts more than others. I did sin and use Papyrus on an invitation recently because I wanted something that was easy to read, but looked vaguely Asian. I like this font (below) because it's somewhat louche French looking and conveys an attitude. But at the same time, it's very hard to read, so I don't use it much. Anything longer than a few words is impossible to read.
There are some great free font sites where you can download fonts without worry of viruses. One of the best thing about these newly-designed fonts is is their names. One favourite of mine is Crack Babies, a crackly version of a traditional font. I use fontfreak and dafont as good sites. What are your favourite fonts? Why?
