Was it ever profitable? I always thought twitter was always in the red and the only time it made money was when it sued Elon to buy it due to his arrogance and coz it minupilated the stock prices on twitter.

You measure your height in metres as in 1.8m or 180cm and for little things it’s mm (millimetres) or cm if it’s less then 1m.

It scales alot easier then the US measurement system of anything other then the simple metric system.
