Three people have asked me to "weigh in" on a new protocol called tent.io. I looked over the site, and I don't understand what I'm supposed to weigh in on. Anyone can write a spec. What matters is what software is supporting the protocol, what content is available through it and how compelling is the content. RSS won not because of its great design, but because there was a significant amount of valuable content flowing through it. Formats and protocols by themselves are meaningless. That's what I say about specs. Show me content I can get at through the protocol, and I'll say something.
