Reviews
Reviews sit on entries. There is no combined feed, and none has been invented to fill this page.
Reviews belong to the entry they are about
A comment is left on a particular entry and stays there, where the person it concerns can see it and answer it. That is also where it is useful: a remark about one person tells you nothing when it is lifted out and stacked with remarks about somebody else. Reading the entry means reading what was said on it.
Why there is no combined feed
Building one is a question of moderation and spam handling rather than of layout, and that work has not been done. Until it has, this page says so instead of showing something assembled for the sake of having something here. A feed that could not be trusted would be worse than an empty one, and an invented feed worse still.
What moderation does and does not do
Comments are released by a moderator before they appear, and reports about them reach the same place. Nothing is written by the directory, nothing is ordered to flatter anyone, and no comment here was produced to fill a gap. When a comment is removed, it is because it broke a rule, not because it was unflattering.
