The main idea of posting things to those platforms, at least to me, is that when I do I talk about hive and try to get people to sign up here where they have a lot more freedom and power to do and say what they want. It’s a bit of our own internal marketing when we as hive users go out there and try to get more people to join the platform here.
Some others though use it to just get exposure and try to make money. I can’t blame them but those platforms can censor you in a second and then you are screwed.
