Yes, forum was and is a good term because it also conveys the roots of democracy in ancient times (a physical place where people met to discuss things of common interest). That was precisely the point a few decades ago: to distinguish between interactive communication media and mass media, which were characterized by one-way communication from a central sender to many recipients.
Unfortunately, however, forum is now a term that sounds outdated because it is associated with the internet before Facebook (2004) – and I would classify Facebook today as a mass medium rather than a social medium, even though, unlike classical publishing media (newspapers and so on), it does not produce any content itself.
Well, maybe he can become the modern Brian Boru and kick some medieval ass in the US — apparently, they can’t defend themselves against the tyranny of the savages.
