I actually read their digest on a daily basis, and used to be confused by this as well. My observation is that each link in the digest actually points to an answer of a particular question. When you click on it, it looks like you arrive at the home page, but the page will show "From Your Digest" at the top so you can actually read the answer. You can then click on the question to read all the answers. It's annoying because if you open a bunch of these links in the background, you would not be happy if your browser crashes, because then you lose all the links.
