Comic Sans is used a lot in the classroom specifically for the purpose of being easier to read for many students, including those with dyslexia. My son has dyslexia and when we were first going through remedial reading instruction, I often printed passages in Comic Sans. It was easier for him. Now he's able to navigate most type fonts.
I don't think it's a professional typeface but I don't have a problem with it.
Honestly, I'm an Helvetica fan. So clean. So linear.
IME, it’s the preferred font for early childhood because the a is similar to how children are taught to write it. I used it for everything I posted around my pre-k room.
This - it does seem like it's a font written by/for young kids, and old-school at the same time. Wasn't it the default for like Windows 95 or something? So my high school or early college papers are in comic sans. I think I just think it's outdated, like wearing oversized flannel and baggy boyfriend jeans... Oh wait, aren't those in again?
If it helps a dyslexic person read their papers better that is great, but I also don't think my company would ever accept it as the default for our scientific and engineering documents, so I'm sorry to those that are dyslexic and working in science industry.
