Too much focus on other people, and it goes both ways. You shouldn't be randomly picking apart other people's companies just to make yourself feel better, that is not moving the needle for your own company at all. You also shouldn't be worried about what other random people are saying about your startup since there will always be haters. Instead you should be heads down focused on your own problems or possibly helping other people who you personally know in private. Posting some criticism on the internet to appear smart or fulfill some other base psychological desire is just a waste of time.
