Here is the feed I created for the DC Best of Blog:

You don't get summaries of the posts, but you do get the titles and links to them, which is better than nothing at all.
Tip: When creating a custom feed, when it asks you to select links on the page, select the ones that lead to the posts, with the titles of the posts.
