Comic Sans has been convicted in absentia by ten thousand design-forum threads, and we would like to file, if not an appeal, at least a character reference. Consider the crime: in 1994, Vincent Connare drew a typeface for a cartoon dog. That is the entire rap sheet. The dog needed a voice, and Times New Roman made it sound like the dog had a law degree.
The sin of Comic Sans was never ugliness. It is sincerity. It is the font equivalent of waving too enthusiastically at someone who wasn't waving at you. And design culture — a culture that once put an entire conference audience in matching black turtlenecks without irony — decided sincerity was the one unforgivable thing.
Meanwhile, the fonts we're told to respect have the personality of a beige sedan idling in a parking structure.
Helvetica has killed more ideas than budget cuts. So no — don't set your dissertation in Comic Sans. But when your dentist's newsletter arrives wearing it, bouncing, dorky, alive: maybe let it wave at you. Almost.
