Roleplaying

[FJerome]

I imagine it would take some effort to stay in-character 100% of the time.

It's more that we're all people who were forum and chat-channel RPers as babies and so we grew-up with the convention that IC talk has no markers and OOC talk has some sort of marker like {{OOC talk goes here}} or some-such. You never quite move on from the feeling that if you're not using markers to indicate OOC talk you're being a terrible person.
