No real journalist should be contributing content on Twitter. No legitimate future journalist should contribute to any publication owned by a billionaire because the economic interests of such rich people are so large that everything they report could effect their botton line. They are affected bu so many issues; ecology, global warming, technology, war, space exploration, everything has an effect on their profits so how can we trust their opinions on anything when every opinion they allow to have a voice is evaluated by lawyers, accountants and whatever other professionals thay employ to evaluate every thought expressed in terms of its affect on the billionaire's interests? It is much like when a President of the United States speaks; every word will be examined by many people to glean any nuance of his/her (her haha!) probable policy decisions. Billionaires are scrutinized nearly as muchas Presidents.
