I'm planning to self publish ebooks, and my primary source of selling would be through affiliates, but there are many so I would really appreciate if affiliates from HN community can guide in identifying best networks and ideas to find and recruit super affiliates on your own?
You need to look closely at your target audience. What are you writing? A Ruby book? A book for geeks in general? A book for sysadmins? All of these would yield different lines of enquiry.
