As writers, we all know the difficulties of getting reviews...too many books and too few reviewers.
Shawn Howen has come up with a solution at Reviews R Us. He sets up teams of writers to do non-reciprocal review which are then posted on sites like Amazon, Barnes & Noble, Goodreads and Shelfari.
The system is simple. You read four books and give four reviews. In return you receive four reviews of your own work from different writers to those you review.
I've found the system good, the reviews written by individuals who understand the craft of writing. This is because the qualification for joining the group is that you must be a published author.
