Since pages can contain comments as well, could we add comments to the /pages view?
We can add that, but given the UI differences between pages and posts, I think we can include them when we get the new comments section sorted out.

@drw158 @rodrigoi what if we just linked out to /comments from /pages instead of building in a UI within /pages similar to /posts?
