After creating your blog, then the next step that you will need to do is to create an account of FeedBurner. FeedBurner is a site that allows blog owners and podcasters the ability to manage their RSS feeds and track usage of their subscribers.
For example, if you subscribe my RSS feed by entering your email address, whenever I have updated my blog, and then you will receive my updates and breaking news via email.
Last time I will not going to subscribe the RSS of any other blog, this is because I hate spam email. But when I have many blogs to visit every time, then I will think to subscribe their RSS because I don’t want to waste my time to visit their blogs without any update for that day.
