In sketching (or mockup) tools such as Balsamiq and WireframeSketcher Comic Sans is used to give that "sketchy", hand drawn look. My only problem is, I'm so tired of that font.
Any suggestions for alternatives?
Edit: WireframeSketcher does not default to the Comic Sans font, but it's the one used to show an example of a "sketchy" look.
Google for "technical font". I like this one.
