have you had that work for you or for anyone yo know? or are you just throwing it out there as a way to do something.
it's easy to say go walk from business to business shaking hands asking if their company is hiring, and yes for a few people that might actually work...but for the vast majority it'll be an exercise in futility.
I know of one person who got a job that way. He was pretty damned good, and had the benefit that he was 18 at the time and didn't know that going door to door "never works."
Congrats to him! 10 cold-calls a day to relevant companies and specific hiring manager (jigsaw, spoke, linkedin) is highly effective at gaining 1st interviews. Linkedin just for "cold connection" or "cold email" contact works very well also. With recent grads / the younger work force tends to apply for jobs outside the realm of their abilities. Such as, 3-5 years of X and X. My own favorite (I was unemployed for 6 months post grad in 2009) was contacting companies / persons and stating something to the effect of "I know you are looking for someone with 3-5 years of experience. I am a recent graduate with 1-2 and wanted to know if you were considering more junior candidates. Could we setup a phone or 1st interview?" Or, volunteering for free.
