I've been playing around with the Known CMS since its authors, Ben Werdmuller and Erin Jo Richey, appeared on TWiG six months ago. I've run my own self-hosted version for a few months, but I've decided to support WithKnown by buying a Pro membership ($100/year - and worth it) and moving leoville.net to their servers.
Known supports the POSSE philosophy: post on your site, syndicate elsewhere (those Indieweb folks love their acronyms). That means Known makes it easy for me to post to a site I own (here) and cross post to Twitter, Facebook, Flickr, LinkedIn, Soundcloud, and more. And with strong support for web standards like pubsubhubbub, microformats, brid.gy, web hooks, and the like, I know this will be a useful and fun place for me to make my home on the web.
Withknown also makes it very easy to export my data for use elsewhere. In fact, that's how I moved my stuff from my server to here. I'm not worried about the future of my content. And I was getting tired of maintaining my own server and software.
I plan to use this site like a tumblelog. In other words, disposable stuff I want to keep. I hope you'll enjoy poking around here. Leave a comment if you have a mind to.
