It's not, but there are a lot of idiots on Twitter indeed. What about NGOs like Greenpeace or Amnesty running their own GNUsocial instance? Alas they think in marketing terms and big reach. But they could promote alternatives. So I have an email template whenever they ask me to share something on Twitter or Facebook. I points them to Diaspsora, GNUsocial and Twister. Please do so too, even if it is only for GNUsocial.
