Thing # 8 RSS Feeds and scrambled eggs-HELP!

My brain

What in the world am I doing trying to learn all this stuff? I am so confused about RSS feeds (still) that I took the night off to rest my brain...now I'm back at it today....

I''m skipping a few "things" (#6-7) because I didn't understand them, now I'm stuck on #8 which is:

• WHAT THE HECK IS A RSS FEED?
• ONCE I'M SIGNED UP- THEN WHAT??
• WHAT IS IT SUPPOSED TO DO AGAIN?
• DO I HAVE TO FEED IT ANYTHING?
• WHERE DOES IT SHOW UP TO DO WHATEVER IT IS IT DOES?

My brain is like scrambled eggs right now...

I have followed the directions to "follow" someone, but not sure if I am or if they know they are being "followed" and I also signed up to Bloglines, which I''m so confused as to what I'm checking off the boxes for!

Can someone help me out there?

PS- don't let me fool you if you see the FOLLOW thingie on my blog, or the SUBSCRIBE...I can push buttons to get them, but I'm not sure what exactly they do....
