Ray Larabie is perhaps the most visible of online fontologists (that's what they should be called :P). I am truly disappointed that they weren't included here.

Yeah no kidding, I pretty much learned how to make fonts with this article by Chank. He seemed like one of the gods of the font-scene in the late nineties. I want to try my hand at making a real typeface at some point, but they're time consuming. I'd spend 48 hours making a font and it would be lucky to have most of the characters.

Seriously. How "amateur" is a list of fonts available from font companies?

Yeah, it's a weird list. You probably shouldn't be considered an amateur if your profile contains the line "while he was studying typography at Yale under the master digital-type designer Matthew Carter". Bit of a white flag there.

Plazm perhaps is a better fit for the article because they're much, much smaller and more amateurish than House or H&F-J. But yeah, if you want to talk about how ANYONE can make a font, why bust out Licko, who's one of the elder stateswomen of the font scene? "Font making is for everyone, look, here's Matthew Carter and Hermann Zapf!"
