What I've done thus far and what I'm trying to accomplish with Affiliate Marketing....

So about a week ago I came here as a complete newbie. Not knowing where to start or what to do. That's when I cam across this warrior forum user who was circulating this PDF book around called "Fast Profit Blueprint" It was a free book so I told myself "What do I have to lose? I at least owe it to myself to try." I read through the first four pages of the book and followed the steps up until a certain part. These are the steps I have completed so far:

1 Opened a ClickBank Account
2. Created a user name
3. Found a product within the niche of e-business and eCommerce
4. I found a product that has a gravity of 20+, Avg %/sale: 50%+, Avg/sale $25.50

(I selected this product among others because it is based on what I am currently interested in learning. The product had a lot of compelling testimonials, a nice introduction video, graphics and landing page like the book suggest. I could have gone with weight lost or bow and arrow hunting but I felt it would be easier and more efficient to start off with something I am already interested in.)

5. I opened my Quora account as an internet marketer to answer questions and concerns of people who have questions about starting an online business at home and generating a 6 figure income.

So the author explains that you have to type: site:www.quora.com "niche/keyword" into the Google search bar in order for it to return searches of people who have posted their questions on the subject in the last hour to 24 hours on the site using the "Tools" section of google. The author explains this is a good way of finding out who has deeply disturbing concerns about a topic and answering their questions while leading them to the landing page of your product. He explains how you go from answering their question to leading them to the sales page but I'm not going to get into all of that now.

The question I have is:

1. Is there any way to do this for Facebook, Twitter or yahoo where people post plenty of questions?
2. Ultimately the goal is to find people who have a concern that you can remedy with your product or have them find you. How can I better use this method given in the book or find a better solution than the one the book is offering?
3. I guess ultimately what I'm asking is once i've choosen the niche I want to be in and the product where do I go from there?

I've tried:

site:www.quora.com "affiliate marketing"
site:www.quora.com "make money at home"

and about 20 others that are within the last hour to 24 hours like the book says. I'm even doing keyword research on some search terms right now

Sorry for being so long winded I have a lot on my mind that I have questions about.
