RSS certainly isn’t dead. I depend on it heavily for work. But it’s definitely dying. Twitter is significantly faster at disseminating news. I find that following various developers, news outlets, writers and so on on Twitter yields faster access to what they’re sharing than RSS. In fact, many of those folks tweet something new before they add it to a blog. I subscribe to several news feeds and their corresponding Twitter accounts. The latter beats the former at disseminating news the majority of the time.
