Kind of a newbie question but... When you build backlinks to your web 2.0 properties, do you link to the homepage or to the specific posts within your properties? For example say you write a post called "how to make money through blogs" and your Wordpress.com site is about making money online. When you article blast, comment blast, etc. - should you link to that "make money through blogs" article or to the homepage of your wordpress.com site?
