> Good TeX should simply yield to good typography.
Making it look like tech can make it appear like you're one of the in-crowd. Although I personally try to avoid exactly that, I can see it being an advantage in -- for example -- CVs. Fwiw, my CV is also done in LaTex. I hope it doesn't show too much: http://stbr.me/cv
It does. It is intended to mimic handwriting in blackboards. I use it for slides when teaching or presenting to informal audiences.
If you don't like it, a good alternative to Computer Modern is Latin Modern. A nice derivative which is not so thin. Reading long Computer Modern texts gets a bit tiring for my eyes. I think some editors like LyX default to Latin Modern instead of Computer Modern.
Aside, The Art of Prolog uses an amazing Lucida variant. It'd be my favorite for math texts if it was free.
I dont like Computer Modern too much. I am very fond of Gentium [1]. For math, I love Euler [2], which is used in Concrete Mathematics.
