Posting this to my Known website is interesting, given that this new Kickstarter project called micro.blog replicates what Known does.
It's a compelling project, and I could definitely see a use for it with a native iPhone app. Known doesn't have an iOS app, so my own site has suffered from the usual neglect that comes with my personal webspaces. I tried to setup a workflow that allows me to publish content easily from an app to Known, but I never quite figured it out.
I've also been on mastodon.social a bit, an open-source Twitter clone. It has a bit of momentum among tech-savvy educators whose work I follow, but the critical mass in my own network just isn't there for me to migrate over from Twitter.
