I’m very close to releasing a Known installer on Reclaim Hosting for people to start playing with it. At that point it would be pretty straightforward for you to fire it up in a subdomain and compare the differences. I do think for someone who wants all the features of WordPress your route is a great option. Known certainly makes much of the #indieweb stuff seamless, although you still have to use Bridgy with it for now, but the comments actually show up in articles as opposed to just links. In fact that’s how I found your post. I got a notification directly from my Known install that you had replied to my post. Federated commenting! I’m really excited about the possibilities of this stuff and I’m glad more are playing with it (D’Arcy just setup a Known install tonight as well).
