More money to the marketing department does not necessarily equate to higher quality or a greater diversity of work. It concerns me that Susan Albert seems troubled about the effects of after market sales/distribution on new authors when perhaps ever decreasing publishing ownership could leave the entire industry in the hands of a few well-off conglomerates. What benefits could there be for the unknown author if all players are catering to the tried and tested middle ground? Thankfully this is not quite the case yet and there are still many good new authors.
I've been registered on BC for 4 weeks in which time I've released three books and have bought 5 new books that other bookcrossers had given favourable reviews. Three of these books were written by authors I had previously never heard of. In these four weeks I've caught no books and it wouldn't matter if I never catch any as I would still benefit from BC.
When a book is published that I think I would like to read then I will buy it. I could be waiting a long time to read the title if I waited for a bookcrosser to release it and the suspense would just be too much!
