I'd love it if the next, extremely influential, paradigm-shifting, best-thing-since-sliced-bread tech innovation just never ever goes public. What's the use of going public? Not everything has to scale up, lose its appeal, become bland and eventually go under.
Twitter seems also the kind of company that can basically be run by 50 people (just like Whatapp). What is the use of all these crazy money injections? Why did Twitter need the money they received from going public?
(I don't understand business or economics one bit, so could be totally off the mark here.)
