I've been invited to try out the new 'conversation platform' Branch, from the creators of Twitter. It's a more structured and controlled way to have conversations about things. And you can choose who participates!
I'm also interested in Branch as a publisher of content as it enables you to embed conversations on your own website - a bit like an advanced comments system. I see it having potential in organisations too - embedded into intranets to facilitate cultural change.
Check out branch.com for more information, and request to join a conversation for an early invitation.
