In 2003/4 which is the period I was writing about there was no Facebook or Twitter and online advertising was not the business it is now. Although publishing via RSS was still relatively new and not well adopted it seemed like a viable way of plugging content together.
Now so much content is in silo's. There are no usable feeds from anyone who cares about advertising because they don't want you to have their content, they want to capture you.
That's what I am getting at. Not whether you can still read some sites that continue to support RSS in a reader.
