While many of us are also relying on RSS, there are a variety of new emerging technologies that are making consuming and replying to content online easier while also allowing people to own all of their associated data. In addition to my article about The Feed Reader Revolution which Aaron mentioned in his reply, Aaron Pareck has recently written about Building an IndieWeb Reader. I suspect that some of these ideas encapsulate a lot of what you’d like to see on the web.
Most of us are doing this work and experimentation under the banner known as the IndieWeb. Since you know some of the web’s prior history, you might appreciate this table that will give you some idea of what the group has been working on. In particular I suspect you may appreciate some of the resources we’re compiling for IndieWeb for Education. If it’s something you find interest in, I hope you might join in our experimentations. You can find many of us in the group’s online chat.
I would have replied in your comments section, but unfortunately through a variety of quirks Disqus marks everything I publish to it immediately as spam. Thus my commentary is invariably lost. Instead, I’m posting it to a location I do have stricter control over–my own website. I’ll send you a tweet to provide you the notification of the post. I will cross-post my reply to Disqus if you want to dig into your spam folder to unspam it for display. In the meanwhile, I’m following you and subscribing to your RSS feed.
