I don't think we need a centralised publishing platform like Medium ever again. Anyone can create a blog for free using Wordpress. RSS feeds are amazing and it can easily serve the job of subscribing to these blogs. Look at the podcasting community for example. It's built on top of RSS feeds and it is thriving. Nobody needs a Medium.com in Podcasting world. What we need in the blogging world are more platforms and apps that are built on top of RSS feeds. Better RSS readers. Platforms that makes it easier to easily find and subscribe to blogs using RSS. Platforms that brings audience to self hosted blogs.
