> I first started using social media (in some form) in the late 1980's with Usenet. I wonder what the definition of social media is which includes Usenet, but not email or BBSs, which presumably Fowler used to some extent as well. To me, social media by definition has some level of participation by users who are not posters or responders—i.e. an upvoting mechanism, a sharing mechanism, or an algorithm based on usage—which changes the prominence of the content in some way. Maybe that's just the definition I've cobbled together in my head.
