I'm working on something like that right now, it's called listhub.xyz.
But I guess I'll stop working on it now that your thing exists. Or we can join forces if you want.
My idea was to be an alternative to all these hand-curated lists we see on awesome-whatever on GitHub and other sites like https://justmeat.co/.
The idea was to allow flexible schemas -- like every link could have a name, a description, another related link, a number and so on.
Later I was also planning on adding a simple API so people could generate static sites with the data imported from their lists.
And also a GitHub exporter so people could maintain awesome-whatever lists outside of GitHub but still keep them there.
Oh, also allow people to suggest items to the lists (with all the required metadata) and have them accepted or not (much better than opening a GitHub issue or PR for the case of awesome-whatever lists).
