Google reader is one of the most popular reader available online now. Google acquired the prerogative right to say the application is best. I am one of the fan of google reader that is why I am regularly posting the tips in google reader. Last week I explained how to make your google reader offline. Actually google reader is ominous for other RSS readers applications, because lot of people are migrating to google reader. A new comer prefer google reader only, you know why? If he / she had a google account, all the application by google are free to use from the same account, thereby google brings the same crowd to all of their applications.
