That's a feature, not a bug:
> Twitter was designed, from Day 1, to enable any random person to send messages directly to any public figure. In other words, from Day 1, it was designed to be an abuse and harassment engine. It's not a bug. It's a feature. All that abuse and controversy is how it gets clicks and money.

Yeah, you are stretching those words a bit too much. It was designed for normal people to be able to get in touch with famous people or vice versa. Some people misuse it and harass famous people. There's plenty of good that has come because of it as well.
I recommend considering the idea within the context of the entire blog post, which is the other reason I shared the link.
Not so sure about this. Wasn't it just designed to broadcast messages among people who knew each other. The celeb focus came later.
I'd also say it doesn't help that your onboarding focuses greatly on what celebs you're going to engage with on the service.
