Good point. One of the most interesting bits of IndieWeb that may show up in 10Cv5 is the idea of MicroPub. There's a quite simple protocol that receives a properly constructed POST and creates a post. I know has got it working into his micro.blog. And the real beauty of it is that there are client apps (definitely for iOS, don't know about Android, but I reckon it won't be long) that can post to any site that is equipped with a micropub endpoint.

Magic!
