Ask HN: I have always wondered...

The point of this thread is for you to ask HN what you have always wondered.

I'll start. I have always wondered why are there no real life chat rooms. Like, when I am bored I can go to a chat room online, and talk to complete strangers. I have always wondered why isn't there a room or area in every community where everyone can go and it is actually acceptable to speak to a random stranger and you can make friends, etc.

What have you always wondered?
