Your comment implies that paying money to hear the thoughts & opinions of smart people is some sort of new concept that should be considered with skepticism. And yes, Twitter does contain more than just political shouting matches by random people.

Here's a few examples:

1. I follow a few photographers that I greatly admire. Some of their best work is on Twitter. With super-follows, I can support these artists and get exclusive posts for things like gear reviews, etc.

2. I follow a lot of economists/scientists that often have really interesting insights. Noah Smith, Tyler Cowen, Ezra Klein, Scott Manley, to name a few. I'd happily pay a couple dollars a month for more in-depth content by them on Twitter.

3. I also follow some interesting writers and creators, like Craig Mod, Hundred Rabbits, and Kyle Chakya. I could see myself paying them a couple bucks a month if enough of their content was offered that way. They are also people I really respect, so I'd be happy to support them.
