What the OP is saying is that Twitter, Facebook, etc. have turned into soap operas.
Nothing wrong with a "never ending story" and there's a considerable clientele for that in older media too. The LoTR trilogies also have that similar feeling for me - I'm left with a bit of a craving after watching just one.
What is, perhaps, new is the immediacy of the never-endingness. One phone-screenful is all you get at a time.
