TV schedules, the things shows had to do for those schedules, and advertisements feel like something I escaped from and I don’t see the appeal of going back at all. The only two benefits to me are: Knowing someone else is also watching the same thing (which could be done for streaming with a simple “viewers” count; and limited selection “forcing” me to watch something I wouldn’t otherwise watch. But that doesn’t really exist in this world anymore.
The idea definitely appeals to me, I just know I wouldn't use it properly. On the other hand, it might be fun to run as a personal service for my own stuff. A Plex plugin maybe.
Have you considered making it a game?
The things I wanted use it for was for Netflix for TV shows and movies, and Yelp for restaurants.
With the restaurant example, the curation can become as strict as dietary requirements (vegetarian, vegan, gluten-free, kosher, halal, etc) that are in some cases regulated by NGOs or government bodies or as flexible as having the same spice tolerance as a friend.
Asked differently, what does the TV channel-like model brings to the table?
but yes, i think you are correct, a curator's list maker would be a better version of this idea.
