You should give some reasoning why not! If I weren't a designer and I stumbled across this, I'd be left wondering why it remotely matters.
I'd also want to avoid perpetuating the sense that design is about preferences, or a few (mostly indecipherable) rules. There are lots of great reasons to use something besides Papyrus, but unless someone knows them, they're just engaging in Cargo Cult design.
I don't think this site is meant to be taken too seriously. :)
