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 like this exists already? I've taken a look at some of the options out there, but didn't end up trying them because it seemed like they didn't do anything like this, and were more focused on simply storing bookmarks (and maybe sharing them with upvotes, but nothing for conversation).
