fricknwill's point is right on. That's a good opportunity for both you and WA.

I think in your niche and considering that you have an entrepreneur page, it fits in perfectly. Plus, you may be tapping into a slightly different sector of that niche than the majority of others promoting in the make-money-online niche.

I haven't yet developed my new site and WA just simply did not fit in with my first niche site. However, the second site will have different sections that are more relevant to entrepreneurship and I plan on adding a comprehensive review of WA. So in other words, go for it! All the best and much success, my friend!

I see nothing wrong with it. People will be searching for certain keywords. That is where they land in your site. You may put a "make a site like this one" kinda spin on it. I see it working well.

I have WA in my sponsor section of my niche site. I don't have a review or any information about it, but having the link still has generated numerous traffic clicks. My newest niche site has nothing to do with making money.
