A couple weeks ago, Digg v1 hit the web and the App Store and one of the immediate complaints was that in order to user any of Digg's special features, like bookmarking articles, saving to your favorite read-later service, or digging an article, you had to be logged into Facebook. The good news is that the folks at Digg were listening and have removed that restriction for bookmarking articles to Digg's Reading List, Pocket, and Instapaper.
