I don't think it's necessarily hated by all designers either. As I understand it, a good designer has many arrows in their quiver and uses them accordingly. In my very limited design research, I got the impression that Comic Sans could give an informal look that Helvetica would be hard-pressed to duplicate.

As far as I can see, this article would like "programming for designers: why you hate Visual Basic For Applications".

Of course, me not being a developer, there's a chance that he-who-speaks-for-all-developers will step in and slap me down.
