Fonts, Text Styles, Sizes, Typefaces....
I’m not going to go into the definitions of the different words. You will find some sites that are picky about the terminology, but most programs use the word Font when asking you to choose among a set of alpha-numeric characters and the word Style when letting you choose pre-set type sizes, colors, and typestyles (bold, italic, etc). The last section of this page includes links to the definitions and information about the history of typesetting - just because I enjoy learning about that kind of thing!

From :
Use simple and easy-to-read fonts
Don't use a lot of different fonts on the same page
Avoid WordArt and other text in graphics
Fonts must be readable when magnified x 200
Make sure there is high color contrast between text and background
Don’t rely on the appearance of the font to convey meaning
Avoid blinking, scrolling, or moving text
(You may see arguments both ways, but...) use sans serif fonts (the ones withOUT little tails).
