| Both as a buyer and seller, I want to know how interested people are in a book. If 500 people have a book on their wish list, as a seller I can seek out that book so I can offer it to my customers (or perhaps I have it in my stock but just haven't posted it).
Similarly if a book is highly sought after, as a buyer I want to know that because it means I'm in some tough competition to get that book.
How would this look in the tools?
Overall - Atomic Avenue mantains wish lists. They must be able to do a simple database query to count the number of wishlists contain each title/issue.
Atomic Avenue: publish the number of wish lists in the top section with other information about the book. (mycomicshop.com does this on the tab they have for adding a book to your wish list)
ComicBase: put the number in the "AtomicAvenue.com" section in the upper right of the tool. As I'm listing books, it would be a big benefit to see there is a lot (or little) demand for a specific book.
Seemingly these additions would require relatively little effort as its already data AA should be capturing and would be a very nice addition.
