Online marketing for job searches

Just posted on my Resume Rehab blog about a woman who is looking for a job using a t-shirt with her resume printed on it. Too bad when I tried to look for her online to find out more, she didn't have a web site, online resume, Linked In, blog, Facebook page... nothing. Given the fact that the Internet has taken over the world of marketing (and most of the world, in general) is it possible for a successful marketer to have a virtually non-existent web presence? Doesn't seem like a very effective personal marketing plan to me.
