I would definitely promise right on the results page that more writers would be added regularly and algorithms would be improved so that people had reasons to bookmark you or to subscribe to your twitter/facebook waiting for their favourite authors.
I would also make local pages for all writers you have. Link to Amazon in that place is unexpected.
You could also encourage showing off by enhancing badges. That could be percentages (e.g. I write like 7% of users) or cool portraits or even something like "I write like Stephen King - I could have written The Stand".
