Alternatives?

If we all agree that MLM’s won’t make us any money, what do you think about click through? Like Google Adsense and the like? This seems a cheaper and less dangerous way of making money?
I post to a blog giving information to writers looking for work, so I post click through banners on the site to try and make a bit of money on the side.
Now I’m not looking for a fortune as in an MLM, but I’m seriously thinking of placing an order for traffic submission to generate a little interest.
What experiences has any body had with this type of marketing?
Does it work?
