On three of the many blogs I regularly read, the bloggers routinely publish their earnings online.If not for RSS, I wouldn't even know about these earnings ! Two of these blogs have landing pages that are way too busy - too much stuff going on - one even has a black background with white text - SMALL white text that is really difficult to read.
Another blog wrote a very nice article about me - that DID NOT appear on RSS! The I noticed several of their posts rarely make it to RSS... very puzzling indeed...
Some of my own blog posts fail to appear on RSS from time to time, unless I give them a gentle "push"...
My own twitter feed is sometimes not picking up new blog posts - that too seems to be hit and miss.
MORAL OF THE POST ::: experiment with RSS and feeds, but do not solely rely on any one feedreader or system. Make certain you don't miss anything of importance to you!
