I don't upvote anything until I've actually read it. Assuming this is the default behaviour of most users it shouldn't be a problem to comment on bad links. If I see a new link with a couple of comments but only 1 point, I'll quickly read the comments to make sure it's worth clicking first. That said, I think adding a small barrier to submitting links wouldn't be a bad thing. Even stopping anyone with 10 karma or less would mean that people have to have a small investment in the community already. Hopefully that would mean they would have a feel for what is appropriate material. EDIT: I just want to credit ichverstehe for the karma to submit thing. My comment was a response to him
