1. Google (mauh, has some good utilities)
2. YouTube (Basically the only available videos platform, like it or not)
3. Facebook (A lot of content that you might not know of is only shared on Facebook exclusively, despite being currently filled with slop)
4. Instagram (Again, pretty good amount of exclusive content, like it or not)
5. ChatGPT(No comment here)
6. X/Twitter, weirdly enough, shit load of exclusive content, despite a lot of people leaving the platform and Mastodon and Bluesky having a better offerings.
7. Reddit.

Regardless if you want to admit it or not, exclusive content attracts people.
