A website today is essential to market your business and ideas. Practically everyone has Internet access these days so you can reach many many people. If you have a message, you can send it out through your website.
I like to call RSS the “Glue” of Web 2.0.
The origins of RSS take us back in time when both Microsoft and Netscape looked at the web as a static entity that could be catalogued, defined and fixed in “channels” (eg Microsoft’s Channel Definition Format – CDF). Traces of the “channel” terminology can still be found in the RSS protocol.
