There has been a lot of stories on how to find a technical cofounder, but I don't recall any on how to find a Marketing or Sales cofounder, for example.
I built a website to gather (all) online learning resources (ambitious, I know), and over the past few months 2,200 users signed up, but almost nobody participates. I'm sure every user has at least a link to contribute to the website, and I made it easy for people to share their resources.
How do I get my users to engage more ? What advice do you have ?
