is Twitter making the Internet local again?

In his fascinating book Spam: a Shadow History of the Internet, Finn Brunton offers an example on pg 23-24 of how the early ARPANET was local in a way that is no longer the case.

in September 1973, computer scientist Leonard Kleinrock used his ARPANET connection in Los Angeles to get back the electric razor he’d left at a conference in Brighton. He knew his friend Larry Roberts would probably be online (logged in at a terminal in Brighton to a mainframe in Cambridge) and could retrieve it and hand it off to someone going to Los Angeles. He reached across the transcontinental, trans-Atlantic network as though leaning over a fence, shouting across the street.

I was struck by the thought that I retrieved a laptop charger in precisely the same way via Twitter. Is this platform making the Internet local again? By which I mean that network activity often forms largely around professional networks with a substantial degree of prior face-to-face interaction and the facilitation of further face-to-face interaction through digitally mediated contact?
