How to link job hunting & social networking

This week I read "The Blog is the New Resume" and "Social Networking has its perks". These articles were very enlightening because I never saw the blog as a resume. But after reading the article I understand why employers would consider the blog a resume. I always thought that blogging was a hobby or something to do with your free time. But then I learned that your blog is a representation of who you are, because it is an unedited version of yourself and it mirrors your thoughts and opinions.

However, I disagree with the second article with respect to if people "want to find a job they should get out from behind their computer". When it comes to job hunting, we need to be creative because competition is high and I think using the computer may actually be an asset in finding a job. For example, having an online presence that is presented in a professional manner, like having a LinkedIn account.

But what I found intriguing, was that the same article suggested using Facebook to market yourself in such a way that makes you appear valuable to potential employers. Though the article acknowledged that Facebook discourages this practice, it suggests that one way to avoid mixing your personal and professional presence would be to have two separate profiles. Now, my question to you is 'do you think this is effective?'
