Blogging is already archaic. The lives of most social networks are shorter than the life of your pet dog or pet cat (they do, however, arguably, for the most part, outlive most hamsters). Facebook, itself, will face its own obsolescence-challenge within 4 years.  Unless it's radically altered into a more embracing framework (totally alien to the current experience), users of Facebook will be rushing soon to download all posts, photos, videos and other remembrances before its closure.  Or they, most probably, just won't give a damn and await the next imminent revolutionary expression of online immediacy. 

So, one might ask, what is the next imminent revolutionary expression of online immediacy?

I have some notions.  However, since I now believe praxis trumps speculation, I await an opportunity to predicate, not simply predict.
