Thank you for the sensible critique. Me and my neighbor were just preparing to do some research about this. We got a grab a book from our local library but I think I learned more from this post. I am very glad to see such great information being shared freely out there.
From my own experience( I can say) yahoo is not the best option for earning, but if you have not a choice, advertising is the best way.
Well, actually that's why I'm asking... I earn on Internet with file-sharing affiliate programs (the most successful experience is now with FileTram). But you know, you're always looking for better, so I always try many new programs and now looking for some info about yahoo. I always thought that with such a big service, you can earn a lot.
