There has been quite a bit of discussion about the question "Peru: to go from Lima to Cusco by bus or plane?"
Now if we apply the criteria from the FAQ, which seems to have changed a bit since last I looked, and the Blog on the same subject. The question falls under the bad subjective category, since it's asking about an opinion from the group, but much rather a vote from the group on whether or not the poster should fly vs. take a bus.
As such these used to be not constructive. Did this change in the since the site went live?
