We're not a commodity and, contrary to hotels, cars, books etc. we have feelings and emotions, and are essentially pretty fragile individuals who really don't need - as the Register has dubbed it - 'slander-as-a-service'. How anyone could think this even vaguely a clever idea, and not a malicious, odious platform for bullying and nastiness is beyond me.
Now, every social platform has its own internal universe of slang terms, in-jokes, unreadable acronyms and memes, and the rules of discourse on Twitter are not those of general conversation. This doesn't, however, mean that discussions on social media exist in an online bubble, isolated from the world, and language, at large.
