I want to know how to effectively go about web 2.0 link building..suppose i have a site on web hosting and i creat a blog on wordpress.com and post an article pointing to my site..then what??

Should I post my 2nd(3rd, 4th and so forth) article in the same blog?? that will make the G suspicious right?? should I create another blog and post the 2nd article there?? Its too tedious and spammy creating one page blogs with links to a site..

I am confused, please help..
