One interesting alternative that I’ve seen is what the social media platform “cent” is doing. Basically every post in the website has a button for donation, you can press it as many times as you want and you will be adding one cent with every click. You can also go to a user’s profile and seed them money, this agreement lasts for a month and you are paying a certain amount of money per day for the month.
Though I don’t agree specifically on the choice of technology (they have implemented their platform using blockchain, specifically ethereum). I think the idea of people being able to simply pay per post or to seed users for a longer time is a great idea. Something similar could be done for platforms like these. I think people are a bit stingy with giving out their money, but with cent you are just giving a cent, it really feels like not much. You would load up your account with, say, 3 or 4 dollars and that’s already 300 to 400 likes that you can give out.
Obviously a website like a forum would probably take 10% or so of the money that is circulating in order to finance itself. Most would go to users but you can always adjust the ratio I guess.
