How about smarter than you, because that is one hell of a stupid position.
I don't have a LinkedIn (or Facebook, or Google+ or whatever) because I don't sit and spew my details all over the internet. For job searches, another reason I don't use LinkedIn is because I have worked with people that I do not want to be associated with. That I have is not important to my looking for a job now.
You don't need a public, updated copy of my resume, you'll get my resume if I'm interested in working at a place. Don't worry, you won't have to worry about it.
I guess another benefit of not using LinkedIn is not working at places that promote idiotic practices such as this.
