You probably wouldn't be able to do this "trick" yourself so I just included the link for you.

 

This is more easy than write a post i think

 

1.1.A web 2.0 site for an affiliate marketer is a place where they can go and join a community of people who are expressing their ideas with one another, and searchers, while making money at the same time.
2."Normal website" Let's say that would be a static page were you don't really participate. In 2.0 you are active in accessing and creating content. You are more involved.
3. No hosting costs, they already rank well, no domain costs, widgets/features that you may not be able to make/integrate into your site on your own. Easy to make a site about any idea you have quickly. Forums to learn from others about that particular interface. For beginners, you need to know nothing about setting up data bases and installing cms. You can start immediately.

4. Most all are hosting for you.
