Congratulations on building it and passing Apple's airport-style security control! I'm also super happy that my work on manyverse was useful to reuse else, that was actually one of the intended outcomes of building manyverse, to enable other mobile apps to be built more easily, to get creative and experiment with cool ideas, and I think feedless has a cool idea (a simple proposition, made obvious in the name!). The node.js backend stack is still quite a wild dragon to tame, but not as wild as ~3 years ago. I'm also open to feedback, to hear what has been easy/simple and what has been very confusing.
Oh, and I'm also learning something new tricks from your code! https://github.com/rogeriochaves/feedless/commit/0433e9c40c06351f18bdbf5826927fe79c6da708
