Just when I think I have something solved..

Hello all,
It has been a couple days since I have worked with the blog, but I need help so I am putting it out there to the Intergods. I am trying to follow along with what our course work is about. Technology seems to have a vast lexicon and it seems like just when I think I know what I am doing, I manage to find an obstacle. The problem is not problem solving per say, but that the problem is circular. Exempli gratia, I think I have the RSS feed part figured out. I was able to add FOXnews without a problem. I tried to go to the two suggested sites for my class (Netvibes and Feedley) and then I get turned around because I am not sure what I am being asked to sign up for. I don't want to sign up, I just want this to work!
Truthfully, I am still trying to figure out what these sites do exactly. If it is a search engine, isn't that what Google is for (or Bing). Can you hear the frustration through the keys?

Any direction would be greatly appreciated.
Peace and terabytes,
Joe
