there's also a whole variety of possible arguments for why someone should get on Twitter, and so far I haven't figured out any clear, universal argument. I think that's your answer. If you can't make a proper, solid argument for what they gain from being on twitter there is no gain, and whatever reasons are left are purely selfish on your part. Or you have just successfully been brainwashed that there is no real world outside twitter. I don't know. Let's just say there is a reason I don't try to convert friends, family and colleagues into listening to Jpop. Not their thing. Why on earth does everyone need to be on twitter? I don't expect everyone I know to be available on cell-phone, email, IRC, MSN and twitter 24/7. Having just one of those is sufficient to stay in touch and I see no reason to force people over to things they don't care about. Anyway, this sounds like mindless, rabid fanboyism to me.
