Share 'Do Authors make good book buyers?'

I just wonder that we are spending quite a bit of time promoting books to boards most often visited by authors. I don't think authors buy many books.I am curious, if it will make more sense to find boards where more readers hang out.  Wish you all the very best. ------------- “Nobody can go back and start a new beginning, but anyone can start today and make a new ending.” http://amzn.to/dMBLWW
