I can't stress enough how many people tell me that no social media app does what they want to do. 

X only works for famous people. Instagram only works for picture-perfect people. Linked-in is a giant circle jerk. Slack is not productive. Discord is a dumpsterfire. NextDoor is barely a glorified classified. Finding good communities on Reddit is harder than finding a good show on Netflix. Facebook only appeals to nostalgia. TikTok is a mindless stream of the same stuff over and over again. WhatsApp groups annoy users more than help. Etc.

Which is really interesting after the billions of dollars these companies have put into developing them. It's almost as if their poorly designed incentive structure led these teams to fully ignore the user.
