What will happen is 'comment piggybacking'. To get endorsed, just 1) enthusiastically support the claim of a 1000+ user and then 2) append your own opinion, making sure it harmonizes with the majority of commentors.
That, coincidentally, is the recipe for groupthink.
That, coincidentally, works quite well in the current system too. You don't even need to agree. Just post your comment as a reply to the top comment or, since your karma might be a bit too low for that, as a reply to the first comment deep enough to have no siblings. I'm not advocating that you do this, but I am asserting that this comment of yours would have been seen by many more people had you done that!
