If you're interested in these new blogging services, check out Medium[1] which is built by the same guy who build Blogger, and Feathers[2] which is also in the "distraction free blogging" space. I like this trend of minimalism and clean layouts but I do not like the same idea being repeated over and over again without good execution (How do I view posts? Where is the post index? Where is the submit button? Where is the privacy policy and ToS? How will you attain user engagement with such an app? Who owns the content?). More importantly, what does your application offer that other applications in this space do not?
