The widely used feed publishing service, FeedBurner, has just introduced the social-bookmarking website, Digg, into its Link Splicing options. Digg joins del.icio.us, Furl, Bloglines and My Web 2.0 for Link Splicing. FeedBurner users are given the option of posting links as they appear or once-a-day. I doubt that I will use this service in my FeedBurner-powered feed; I like to keep mine clean, which is why you don't seen any new-fangled YPN RSS ads or AdSense for RSS as I talked about over on Performancing.com. If you are wondering what the point of adding your daily social bookmarks is, take a look at Steve Rubel's Ten Blogging Hacks.
