There's a difference between properly and pedantically, Kali.
And when you say the font should have its weight changed, you're actually saying it shouldn't be bold, right? Use layman terms, srs. It's been four years since I took that course, and it wasn't in English. I thought you were referring to manually slimming/thickening
parts of the individual letters.
To be honest, as long as he's going with the white background, it doesn't hurt to have a, um, heavy(?) font. Reduces the amount of visual noise you get from the white. I'm sure it's horrible from an art designer's point of view, but you have to factor in functionality as well. A pretty website isn't worth a lot if the viewers burn out their corneas the moment it loads.
As for fonts, Bleeding Cowboys and Curlz MT are logo fonts. No one in their right minds would write an entire paragraph or more in that. I know my sister once did in Curlz MT, but she was 12 years old and it was back when wRiTinG LiEk tHiS wAs aLsO HoT.
Kali, most website designers most likely stay within the reasonable range of fonts. The fonts they know and like. My guess is fonts like Bleeding Cowboys and Curlz MT aren't on that list. But to argue whether it should be bold Arial, regular Verdana or Calibri... that's pedantic. Not necessary.
