My personal take is that over all, `application specific` social platforms (SP) are working just fine like Github (SP for coding) and Yelp (SP for local listings). There's a general goal that people go to get the resources they desire. However, Facebook as come to be a `SP for media`, which is why its generally known as social media. There's just no general purpose on FB other than to share media articles nowadays.
