Surf.social is a great service so is Channel.org. I can see how they can interoperate too. What I think Channel.org has over Surf.social is a website/Web App that people can build channels on via their computers and aren’t stuck using a mobile device.
Now I know Mike over at Flipboard/Surf has a website/Web app on the roadmap. But I’m impatient and can’t wait! LOL
Though it is a great mobile app.
