alt Hacker NewsThis website absolutely is social media unless you’re putting on blinders or haven’t been around very long. There’s a small in crowd who sets the conversation (there’s an even smaller crowd of ycombinator founders with special privileges allowing them to see each other and connect). Thinking this website isn’t social media just admits you don’t know what the actual function of this website is, which is to promote the views of a small in crowd.
To extend what 'viccis' said above, the meaning of "social media" has changed and is now basically meaningless because it's been used by enough old media organisations who lack the ability to discern the difference between social media and a forum or a bulletin-board or chat site/app or even just a plain website that allows comments.
Social Media is become the internet and/or vice-versa.
Also, I think you're objectively wrong in this statement:
"the actual function of this website is, which is to promote the views of a small in crowd"
Which I don't think was the actual function of (original) social media either.
