Joebhoy: I always say that RSS feeds are the best internet marketing tools, even more effective than social media and search engine optimization.
RSS feeds (really simple syndication) is really just that. You are syndicating your blog or web page content onto other websites and mobile devices. There is nothing on the web more powerful and effective than that, so say you have 1,000 subscribers to your blog and all those subscribers are connecting to their mobile device to your RSS feed (iphone, blackberry, android all have RSS feed reader apps), then those are 1,000 people who can read YOUR content instantly every single time you update your blog or website. How cool is that?
Do you see the benefits of this now? I also have some hubs on RSS feeds that you may want to read.
