Here’s my response: 1. I have no idea if the Facebook platform is alive or dead. I’ve got left-over MREs from Y2K, however, so I think I can survive its demise, if it should occur. 2. Asking people if they use RSS is like asking people what size air filter goes in their car. RSS is now entrenched in the infrastructure of the sharing web. It fuels widgets, it automates blog posts, it enables all sorts of gizmos and thingees that the average web user would never recognize as RSS. Nor should they. Web users should click on a button that says, “bring me information about this topic or from this source.” How it gets delivered will probably involve RSS, but who the heck cares.
