I am using blogger for blogging and i am having some problems in my rss feed. 1: I have heard that there are two urls for my rss feed i.e. http://yourblogname.blogspot.com/feeds/posts/full http://yourblogname.blogspot.com/feeds/posts/default?alt=rss I want to know what is the difference in both of them and which one is better. 2: Feed validator is not varifying my second url of feed while the first one is right. What might be the problem in it. I am not using feed burner for creating my rss feeds.
