Several years back, perhaps even via an HN post or comment, I came across a blog, hosted on a university network (IIRC, perhaps related to media studies). The page consisted of a group of possibly graduate students contributing some of the weirdest and most obscure media I've ever seen online. Nothing obscene and nothing seemingly new/current, so it was rather hipster in that sense, but I kick myself for not having saved the URL.
Nothing says I need to use walled gardens or get my news from the big networks, but I often feel I'm being pointed that way. In the end, I just want something different than what's usually being served up.
(It doesn't escape me that this 90's TV site is full of walled garden/big network type content of the time)
You can have that. All you need to do is make sure the developers who make those sites get rich. Find the sites and tell your friends about them. Subscribe to their work. Buy their merch. Click on the ads. Pay them. Then everyone else will see that sort of site making bank, and they'll follow along with similar things.
The only reason the web is what it is today is because the money went to the walled gardens and social media sites. To change that, change where the money goes.
