alt Hacker NewsIt seems to generate pretty good "Recommended repos for you" suggestions, all of them I've heard and seen before, but for one or another reason didn't use for anything or found a need for. Would be great if it could show more options than just 10, because I'm sure further down the list it'd have interesting suggestions I hadn't seen before.
Sounds like it actually generates poor suggestions for the reason you are describing. For me, it exclusively suggested repos I've already seen, but did not like.
