Ryan Holiday’s Our Regressive Web is the best thing I’ve read so far about the importance of services like Google Reader and Delicious. He starts off with this statement:

The collapse of these services, to me, represents an alarming reduction of key services designed to improve online information from the user’s perspective.

Ryan explains how RSS helps to reduce noise and clutter, and he provides a theory for why it never really took off beyond geek circles:

In an ad-impression and pageview-driven business, a service that allows users to opt out of the noise and get content delivered directly to them is dangerous.

Maybe I’m just suffering from confirmation bias because I’m still pretty bitter about Google Reader’s shutdown, but this is a really good analysis. Well worth reading the whole thing.
