Twitter is international. It will not have the same appeal with segregation by nationality.

The Dutch Government has a much higher trust rating than ours has. Can you imagine the same uptake if the UK did likewise. I certainly would have zero trust with the current people in power.

Sciences, sports, politics, news and many more all rely on twitter as a platform that works or used to. There really is a case for a internationally ran system for this. Twitter has such a high value that removing it will have a negative impact. Something that has become so fundamental to getting a message across needs to be ran in a not for profit fashion, rather than see it go to the wall because there is not enough return in it.
