I joined WA many years ago. I have built several websites overall, some for affiliate marketing and others for other reasons.
I found that if you write three quality posts each week for one website, your traffic will be enough to support you after 6 months to a year.
I do not spend a lot of my time here, I will answer your questions if I can.
Chris2005's Goals 3
Any money would be a good start. $1000 a month would be my first goal. The ultimate goal would be $2500-3000.
