I think I would enjoy something like this (or pinboard), but with comments. Sort of a smaller version of Hackernews, where I could see what my friends are bookmarking and then write comments on those links, so we could chat about the content not necessarily with random people of the internet but with your smaller community (or maybe with everyone too, but in a different section). Maybe someone here knows if anything…
Would love to give you an invite! I think my email is in my profile, if not my DMs on Twitter are open (@TheOisinMoran).
I also just added this to my "lynkmi adjacent" tag too for other related ones to check out: https://lynkmi.com/oisin/lynkmi%20adjacent
