Fonts: Because not many know much about them.

    There are standard "professional" fonts like Times, Georgia, and Trebuchet. Mainly Times. But to be honest, those are boring and hard to read, I think Comic Sans is much better, it's made to be dyslexia friendly. Arial is made for the same reason, but for me, it's still hard kinda to read. I find Comic Sans much easier to read. however, I know one person can't change the standard of "Professionalism." But, take into consideration, It's not only people who have dyslexia who find might find it better, but also other neurodivergent people. I personally don't have dyslexia, but I find it much easier to read things in Comic Sans. Even if it's seen as "Childish" because what's truly childish, is defaming an accessibility tool because you think it's childish. Or, unprofessional. And one could say my stating that is contradictory. But, take notice, that even though I find Arial hard to read, I am still using this font, because others view it differently than I do. I would much prefer having Comic Sans as an option, however, this is the best I can do to make my writing more accessible. The thing that differentiates me from them is that I know that others have different opinions. And that it's okay that they do. So many others are stuck in the state of one being "right" means the other is "wrong". However, that is simply not the case.
