I like RSS, i think it can improve the information diet people have by getting high quality content. kinda an alternative to more popular content (meaning possibly low effort) pushed to us using algorithms or just created to appeal to the masses because it is more economical.
It does have a UX problem, i think we need some open source project where you click on a button and it will show you the RSS address but also give you the option to set up RSS while it coaches you to do it in a way that is kinda pleasant and easy.
We need better funding for open source games IMO, maybe a non profit set up for that.
