Love the article, Linda! It's very true that people buy based on emotion. I consider myself part geek, but when it came to buying my most recent cell phone, I didn't care about the technical features - just that it looked pretty. Now guess who's paying the price of poor reception, horrible phone book functionality, and other such wonderful things?
I think the best point in the article is the part about "Thinking “if I build it, they will come”." Unfortunately this is simply not true, and knowing how to market your site is key! Luckily affiliate managers can help new affiliates with that.
