The news of Google Reader's upcoming demise has put the spotlight on several alternatives that RSS fans can only hope will fill the gap. The latest to vie for our attention doesn't even exist yet: Digg just announced that it will be creating a reader of its own. According to its blog, the aggregation service was apparently already planning to build such a reader, but upon hearing that Google's version will bite the dust, the company is kicking into gear to develop a suitable replacement. Digg's reader will maintain what it calls the best of Google Reader's features, including its API, while incorporating changes that reflect the relevance of social networks and other popular Internet communities.
