Typically questions linked from a news aggregate site are closed because the question is now a stage for people to shout "me too" without reading the other posts. We end up with dozens of comments that haven't added any value to the discussion. If one of my questions are linked, I request a mod lock it, because it's damn annoying to have my inbox flooded with that kind of feedback. Protected locks are removed after a short time, if you feel strongly that you had a meaningful contribution to the post.
