I came across this slide by Kyle Neath (https://speakerdeck.com/kneath/how-do-you-build-great-software) and about slide 52 onwards, there are screens of what I imagine to be an intranet-like website/wiki github uses to help new people get up to speed.

I love it - it's simple, elegant and the "team" & "ideas" sections just blew my mind.

My question: Is there anything similar like this out there that exists? Does your startup use one? Did you feel a need for one? Did you build it yourself? Can I get a hosted solution?

My previous startup went with a bog standard self-hosted wiki which I think didn't go too well with the non-techies in the team. This is why I love what github has got going on.
