This is a great exposition on the beauty an utility of RSS. The open web is being shunned by most large consumer-oriented “public” spaces these days so that the can control the user experience and try to capture the benefits of network affects. It doesn’t have to be this way. You can build a great service and also provide open access. The reasons for not doing so may make business sense in the short run but in the long run you’re only alienating your business from the rest of the web and the opportunities for larger network effects.
The open web isn’t going away. Developers should embrace it, not shun it.
