hi guys,
thanks for the link, it seems that your question posted here, and the one in the Google+ conversation are not the same.
i thought you were asking about duplicates, and just wanted to stress that we simply suggest related content, and that what publishers do with them is entirely up to them. if spammers or anyone else takes that content and re-publishes it, it's a problem that we all have online these days.
the lower-quality links question from Rich is different. I have to defend our user base here, their profiles and their editorial control. we are making sure that only real-life bloggers are using our tools, for real-life posts. of course they will be of different quality, but we've learned that 'quality' is actually not easy to define, so we decided to rather focus on authenticity.
and on the other hand, of course seo professionals would prefer to have control over their links, but we will not allow for it, because the choice to publish something or not has to be editorial decision of the author.
i hope i'm not missing something
best, b
