I know this is probably a stupid question, however I do believe I don't quite understand how RSS and all that jazz works.

Lets say I come across an article on another blog that I like and I feel the article and keywords used in it may be a benefit to my own subject. Is it right that I would somehow see their rss feed and feature an excerpt from the post I like on a post of my own and I would then write a discussion along with their post on my own page? I look at RSS feeds and they seem to show many many posts from the authors... or am I looking at this the entirely wrong way?

Thanks in advance
