Danny Ayers is really grokking the idea of Feed Grazing and I love the del.icio.us mashup he's done to produce a dynamic OPML Reading List. The next step is to produce dynamic OPML hierarchies and we'll be well on our way to Web 3.0 (Ok, ok, maybe just 2.5 ;-)
After Danny and Richard MacManus took up the meme of Feed Grazing yesterday I received a few emails asking me to expand on my views. In order to do so I have to first clarify my own mental map of where we are. My own definition of Web 2.0 doesn't depend on AJAX. Although AJAX is a hugely important development I think Web 2.0 is more about behaviours than interfaces. In fact I'd roughly equate Web 2.0 with Doc Searls' World Live Web.
Based on that perception, see the table below for my draft view of where Feed Grazing fits into Web 3.0. It should be noted that I don't see Grazing as replacing Aggregation, but I do think it will become the dominant method of access to feed information - especially in an RSS-everywhere world.
I'm well aware that there's little new thinking here but I just needed to clarify where I see Grazing fitting in. And it should be noted that there are plenty people, like Mark Wilson, who think we'll go in the opposite direction to Grazing by investing more and more in subscriptions through social bookmarking.
