No we can't, no it's not, and no it doesn't. There are many other fun, comic-y faces that aren't terribly designed.

Could you point out what objective qualities of Comic Sans makes it "terribly designed" when compared to other "comicy" fonts? Look, I'm not a particular fan of Comic Sans but I think the bashing of it is borderline childish given how many unreadable fonts there are.

Could you give some examples please?

Examples of alternatives? Glad to. Blambot(1) makes a range of great ones, especially Giant Sized Spectacular, and I'm personally partial to Loose(2).

These fonts (1) certainly look good but they are very different from Comic Sans, almost too pro. I think none of them capture the childish, random, non-professional feel that Comic Sans visualizes. I can understand why people loath Comic Sans but as I said, it has it's uses where more professional types fail.

I recently saw Comic Sans used in one company's printed invoices. I though it ridiculous until I discussed the topic with the people there. They actually made a very tactical decision in using the font. It was all about the feel of it.

Come to think of it, perhaps I'll found a fan club for Comic Sans. :)
