A C Goodall feels the limits of the site:
Twitter functions as banally as a school hierarchy: who to like, who not to, who you're allowed to criticise, who you can't etc. Whilst Malcolm Gladwell's article in The New Yorker last year enraged many with his claims that social networking was not instrumental to social change, his most salient point was that social media is "not the natural enemy of the status quo." Twitter relies on people's desire to be the same.
Alan Jacobs rejects the claim:
Twitter is a platform and a medium, not an organized and coherent body — it’s not like a book, for instance, which can be said to have a single overall character. Imagine what you would think if someone said, “Email is all about fitting in.” Or “The telephone functions as banally as a school hierarchy.” Or “The telegraph relies on people’s desire to be the same.” Media platforms are what you make of them, and the history of each reveals that its makers expected it to have a relatively narrow set of uses and were surprised when people exercised their creativity to find remarkably varied uses.
