Great questions 1. Github projects are just one example. Other example might be for a journalist, his article ; for a photographers, his 500px or flickr stream, for a researchers, his courses, university or google scholor links.

Monetization is something we do think about in terms of areas that would not compromise with the premise of the network i.e users first. For example if the contact form works, recruiters will pay depending on how many forms/invites they can send, so like 25 free per month but then pay for next 5 till you hit the monthly cap(Yes cap please). But needs more thinking here
