I feel increasingly angry/frustrated at how academic conferences insist we 'join them on XTwitter' to follow the conf. Why should we have to do that? Why arent they providing an open social web alternative? Why are they so beholden to private monopoly Big Tech? This happened recently for the Networked Learning Conference, an initiative that claims to be dedicated to open networks of learning. How can they possibly think it is ethically acceptable to only use XTwtr?
