Well, it's a tough call. I agree that communicating trough them strengthens them because of the network effect. But if you never reach "unaware" people with your ideas where they are (on those platforms, that is), you are not really helping either.

So it's not clear using those platforms only hurts. It could be a net win, all effects taken in account.

In any case, I agree that you should not force people to use these platforms to follow you.
