I think the part that is missing is how to discover the link collections to subscribe to.
I'm building https://linklonk.com that merges the collection, the consumption and the discovery:
- You add links to content you liked to your "channels".
- LinkLonk connects you to RSS feeds and other user channels that posted the content you liked and shows you new content from them. The more content you have in common with a feed/channel - the more weight their new content gets in the "For you" list.
You can also share your channel via a public link (example: https://linklonk.com/channels/programming-yUlhkwDXFb) or an RSS feed (example: https://linklonk.com/api/publicChannels/programming-yUlhkwDX...) .
