How Do You Build a "Proper Blog" and Make $$$ for Noobs

Hi everyone.

First of all, I'd like to say I love this site and it seems everyone is very helpful, especially to newbies like me. Here are some questions that are probably very common knowledge amongst all of you, but to me, its like trying to read a foreign language. So bare with me as I am trying to learn and understand. Okay, here we go....

* What is the major difference between, say a Google Blog and the Wordpress everyone is talking about?

* How are people making money with Blogs? (As you see in mine, it is very generic and just a review of a product I use and like. But havent added any content in quite sometime, guess Im waiting for traffic to fall out of the sky)

* Are most people making money from their own products or reviews on affiliate stuff?

* What exactly is a RSS feed and what does it do? Advantages?

* What steps should be taken to get traffic to the Blog itself?

* What is some of the best content to add to your Blog?

I had a few more questions while I was lying awake and couldnt sleep, maybe they will pop back in my head after reading some replies.

Thanks in advance
