David Kadavy: Why you hate Comic Sans

Problems with Comic Sans:

1. Unbalanced visual weight in both the letter-level and paragraph-level.
2. Bad kerning (spacing between characters).
3. It gains undeserved popularity nowadays with an aged design for on-screen display in 1994, during which Windows 95 does not have anti-aliasing.
4. Average people mistakenly think they can design well with the ease of modern technologies, while professional designers fight back intensively. And Comic Sans is one of the fiercest points of conflicts.
