A social media site’s dominance should affect how it behaves

Letter in the Guardian, 6 August 2013:

The rules for social media sites should consider their size and market dominance. Consider a town with several pubs. Behaviour tolerated in one pub may cause some to drink elsewhere. But if the customers have nowhere else to go, it seems reasonable to expect the landlord to adopt a more interventionist role. Sadly, the way Mark Luckie, Twitter’s manager of journalism and news, withdrew when subjected to a fraction of the abuse endured by the people who indirectly pay his salary shows corporate incomprehension of this responsibility.

Why not provide tools to formalise natural tribal segmentation, as noted by Professor Vincent Jansen? That way we can all choose which pub to chat in and avoid the boors as well as the bores.
