Paid blog reviews for the majority of bloggers will not come to fruition in a big way.

That's a bold statement. Here's why I'm sticking my neck out: Many bloggers are keen to have their sites reviewed but they're not willing to pay for such reviews. Why should they when there are blog review sites offering free reviews with links thrown in for good measures?

Likewise, there are plenty of blogs doing voluntary reviews of other blogs. Usually they will pick on blogs that they feel are similar to theirs. Or for the simple reason that a particular blog has great content and information that makes you want to write about it. I'll call this "goodwill gesture" and it'll also help to build links and traffic.
