Right now, the biggest shared value that I can think of is that you should treat others the way you want to be treated, and just have some good sense about what matters to you.
Craigslist does serve as a platform where people help each other for the basics, and also, shows people that the Internet is good for mutual support. I do feel pretty good about that.
Milestones aren't what I think about much.
Do something real, and keep it simple.
I'd like to build a way for people doing good work to connect, to learn from each other, protect each other, and then I want to get out of their way.
