Mystified about the orange button emblemed RSS Feed on various blogs. Let me solve the mystry for you. Blog feeds or Really Simple Syndication ( RSS ) is a way to aggregate varius blogs which you visit at one place. So that yo can read all the stories without visiting all the sites. So it is a headache avoidance act for you. What you need to do for it is subscribing the RSS of various sites by clicking the orange buttom. You also need to have a reader which are of two types. Desktop reader anda web reader. WEb reader is more popular if you want to access the stories from the internet using any computer. So far so good. If you want there are services available, popular ones being bloglines,Yahoo,Google, Newgator.
Logging off for now Happy Blogging.
