Book review bloggers can give you some exposure and name recognition. I've not yet bought a book that was recommended in this way, but I have picked up several in the library because the cover and title were in a recent review--which in turn moved me to pick up the book and read a few pages to see if I might like it.
Amazon reader reviews can be influential as well: I've bought a number of books based on multiple (high) recommendations.
