LOL He is right. If you plan on making a free "how to make moeny" blog site that has a big list of affiliate programs and products mixxed in, you've been beaten to that idea already! Maybe spend a few weeks making affiliate pages for specific products, learn some techniques so you have some ammunition, stories and original content for your blog!
The world needs more "Make money from home" blogs that is for sure. After all, someone must be making money from home, right?
