I did the same thing with Yahoo! Pipes here that I did today for the Reference at Newman Library blog so you can subscribe to a feed that gives you all new posts and comments. If you’d like to see how I did it, I created a screencast and wrote step-by-step instructions on this post from my other personal blog, Stephen Francoeur’s Stuff.
Here’s the URL you can add to your feed reader for the new combined feed:
