Bum marketing is, in essence, article marketing. You write informative articles that contain a link to your landing page/website. Then submit those articles to article directories. Readers of those articles will hopefully click on your link and eventually buy the product that you're promoting.

It means you're doing affiliate marketing solely using article marketing strategy and you're actually writing them by yourself.
Bum marketing is good for newbies, who are struggling in IM. Squidoo + article writing ( on specific keywords, related to your niche ) = bum marketing.
If you're a newbie in blogosphere, then bum marketing will help you to build so many useful links. Try to concentrate on these lines to get more links...
Taking homeless off the streets that have those will work for food signs and having them write and submit articles for you on their laptop.
Because so many bums have laptops Though sending them to the library could prolly work. As could simply having them put your URL on a sign. WILL WORK FOR FOOD digitalpoint.com
sad to say but if i seen a bum holding a sign that had a url on it i would prolly go their to see wtf was going on.. lol
So would I... so would most of the people I know. Maybe try it? What could it cost, $5? $10? that's cheaper then the clicks it would cost with Adwords, lol ^_^
