Sherif, you are so right about the reviews. It's so obvious when I go to a site and the author recommends everything. Usually I know they haven't bought anything and they only want the commission. But when I see a site that actually has negative things about a product and doesn't recommend everything then their credibility goes up in my book.

Allan Gardyne is a great example. Yes he pushes a lot of products with his affiliate link but he's not afraid to say when he doesn't like a product.

And the more specific the review the better. You can't just say "I didn't like the product" or "I loved the product" It's important to explain why and it's always obvious at who really bought it and who didn't.

Excellent points.
