I have an email list of about 10k hackers & engineers who I send educational stuff to now and then. I've tried sponsored ads, which was fine, but the amount of ads you can show without making your users angry is pretty limited, so I'm wondering what else I can do to monetise my list in a bit more scalable way?
Launch some kind of product hunt or linked in type site. Probably need to be different in some way.<p>Maybe send them a survey you'll share with the group on sites they use, like and what's missing, etc.
