Perhaps Kinja wasn’t a bad idea for a CMS cum commenting system, it just wasn’t open web enough?
As I read this, there are some underlying ideas that again make me think that newspapers, magazines, and other journalistic outlets should pick up the mantle of social media and help their readers (aka community) by providing them with websites that they can control and use to interact. Many newspapers and other outlets are already building their own CMSes and even licensening them out to other papers, why not take the next step and build a platform that can host and manage websites for individual users? They’ve got most of the infrastructure there already? Why not tack on a few simple things that allow their users to better interact with them on the open web. It solves their ownership issues as well as their reliance on social media silos and could even provide a nice, modest income stream (or even a bonus that comes along with one’s subscription?)
