I imagine you can stuff WYSIWYG into a special purpose client for "Other Stuff", but most clients focused on social media would still just render as plain text.
Curious idea. Wonder how folks with a higher technical acumen respond.

Might make a lot of sense for encrypted events that nobody else can read anyway.
And/or a file system where you share access.
