I hate Comic Sans, not because it's a bad typeface, but because it's misused.

It's a playful font, so using it for playful things is great! Anything related to children's activities, it's a fine choice.

But then people use it for things that aren't playful. A sign at your bank saying they're low on coins should not be in Comic Sans. Work e-mails should not be in Comic Sans. A resume should not be in Comic Sans unless you're applying for a literal clown job or Kindergarten teacher.
