I have always wondered why Facebook and Twitter are jumbled into the same category. Messages posted on Facebook are to a closed audience by invite only.
In my mind it's essentially the same as telling someone by speaking to them or calling them. Whilst the question of whether that act itself is libellous does exist, I think it mutes the point of saying that a Facebook post is a piece of published work in the same way that a tweet can be compared.
Am I missing the point or is this another case of tech-foolery?
