I downvoted you not because you disliked the typography, but because you chose to attack the poster and not the content. You can dislike the typography all you like, but I can't fathom how you read OP's message and got smugness or vanity. What part, exactly, was smug or vain?

You wrote: "I get that this is a hobby for you. ..."

But then demanded a non hobby level of commitment to the craft.

"..But the arrogance and vanity of software folks who think they can do typographic design (without any training, eye for type, or respect for the real skill and tradition of typography) "

So how does anyone get _in_ to typography, exactly? Is it by having it as a hobby and moving forward or is it only available to people who complete apprenticeships? Who are you to deny anyone their hobby?
