Sarah Perez from ReadWriteWeb posted an interesting article called 'The Resume, Rebooted: A Look at Web-Enabled Job Hunting' in which she covers the latest in dynamic, multimedia-enabled, online resumes.
And while she did cover social networking, she didn't mention the power of blogs, or even a personal website, in helping people get jobs...though, come to think of it, that could have been outside the scope of her article. Anyway, the jury is out on whether any of this online stuff does indeed help people in the general population get a job. I would, however, contend that, for people in the web world, having stuff about you online is crucial. And if that stuff by or about you is good and positive, that's even better. After all, on the web, all you often have is your online reputation.
