Earlier quoted context omitted.
The difference between the telephone company and Twitter is that the phone company was (historically) a monopoly - the only game in town . Use their wires or get lost. It required common carrier neutrality by regulation. Twitter (and every single commercial social media space) is not the above, and can do what it wants on its service. It's not a public utility.
> the phone company was (historically) a monopoly Phone companies are natural monopolies on account of the cost of building out a physical network and network effects. Social media has similar dynamics. The only difference is there is no requisite physical layer.
Is there a network effect? Sure. Did MySpace, Friendster, AOL, CompuServe etc have those first mover advantages as well? Where are they now?
