I presonally think that it is an unworth attempt to get quality traffic and uniques.
Even if you get 10 thousands of visitors every week from this method, I'm pretty sure they cannot be converted into anything else.

You can, of course, disagree with me; but I would like you to say why it's good/useful.

So what are your opinions? Did such a scheme ever worked for you?


Cheers,

Nic.
