I now see that I expressed my idea unclearly. Sorry!

I don't have any RSS feeds specifically for new/good apps. I meant that in my normal RSS feeds, sometimes new/good apps are mentioned that I want to take a look at.

I get leads from sites like selfh.st, Lemmy communities that discuss FOSS or Linux (or even non-tech-related communities sometimes mention an app that has to do with their domain of interest), and I sometimes search github (FYI, I use github as little as possible - I host my own Forgejo forge for my stuff - but, like Youtube, you have to go where the data is if you're going to find the data).
