There really wasn't an argument put forth beyond "he's bad at business, can't you see it's obvious". His tone and lack of content other than an unsubstantiated opinion are why there was no interesting discussion.
I never said "it's obvious" in any way shape or form, but I do believe this is my stop. Have a nice day.
It was not unsubstantiated. If I define a good business as a business with profits, this definition has a lot of substance. Jack Dorsey obviously achieved a lot of personal success and money from Twitter, I am not blind about his amazing achievements. Amazing because they are statistically difficult to obtain at this scale. BUT, being a public company is a different stage of the game. As an startup you can be amazing while the finances are hidden but when you are public you need to build a sustainable business and this is not happening.
