I love Comic Sans because it pisses off hipsters and pretentious (read: all) graphic designers. I don't see what is wrong with it, and the major complaint I see is that it is used everywhere - which is nothing against the font itself.
That's true, I was SO pissed when I saw that most text on my diploma was written in Comic Sans, four years ago. Like I couldn't even use it to employ myself.
Comic Sans isnt a bad font, however its use should be limited. In terms of most graphic design, fonts like comic sans and papyrus are evil. Could you imagine buying a product written with comic sans? Im sure its out there, and it usually comes off as 'cheap' and 'kiddie' looking. I think it should stick to birthday cards and comics
