Here's what some others have said about resumes. Specifically as to whether or not they could be replaced by blogs.
"A blog, in my opinion, is nothing more than a preview or an overview of a person's experience and will never truly replace a conventional resume. I am working primarily with candidates that have the highest Government clearances and a formal resume must be presented and in some cases formatted in a prescribed template issued by that given intelligence agency."
"Blogs are useful backup collateral and an interesting guide to how passionate and up-to-date candidates are. However, we still need a succinct, all-in-one reference document and the resume provides us with this. It is worth remembering that resumes often only get scanned, so it is the hook that catches a headhunter when they are searching their database or applications.
"I think the biggest issue is not the resume itself, but the lack of quality in many resumes. Many list a series of responsibilities rather than highlighting achievements; a fatal error, leaving too much to the imagination.
"It is estimated that only 20% of opportunities are publisized, but unless you are hiring a family member or best buddy, sooner or later you will have to get your CV out. I can't imagine anyone worth their salt hiring without seeing a resume and taking up references."
"Resumes are very much alive and well. As a ten-year, seasoned recruiting veteran, who has used the newest technologies to find candidates, such as LinkedIn, I still prefer good old-fashioned resumes by far, especially when dealing with large volumes of candidates applying. I do not have time to go to a candidate's blog, LinkedIn profile, etc., to get what I need and then have to ask for a resume anyway to send to my hiring managers and interview team members. I use my one hour phone screen to best help me decide who are the best candidates I will move forward with. Resumes have worked for me over ten years and they still work now. I just placed 33 highly qualified candidates at one of my high-tech, cutting-edge software clients using just resumes and phone screening, without having to waste unnecessary time wading through several LinkedIn profiles and blogs. My vote is still most strongly for use of resumes."
"With over 20 years recruiting experience, I know without question that a resume will continue to be valued and required. No experienced hiring manager or recruiter is going to spend the time reading a blog to make a decision on a candidate; it is just not practical in many situations. The ease of distributing, printing, scanning and quickly reviewing a resume provides several advantages over a blog. A well-written blog may become more of an asset, but it will not be replacing the resume any time soon."
