It's not hard to be intellectually honest and negative. Negativity also performs better than optimism on social media.

Much harder to be intellectually honest and optimistic with bias for action, willingness to fail, learn, ability to find the appropriate amount of signal in all feedback and then discard remaining noise, and most importantly, not quitting.

A platform has to deliver to its target market; it cannot change its target market but has to change for its target market. If it wants to be positive it has to reward it as that’s the harder work. If it doesn’t do active work against the negative, it will be overcome by it because it’s easier. Just look at how hard it is for a leader of an organisation to keep its own goals focused and keep positive against the entropy of its own people’s thoughts. The problem with pursuing scale is it makes the tent bigger and bigger and starts to have to include the negative as a market segment. Pursuing scale may move the positive goals into conflict with the scale goals. So, you need to know the goal. Positivity or scale?
