This can scale but not without a lot of people doing a lot of work that they want to do. And they need to care about the people on the other side; whether they are job candidate you don't hire or employers you don't want to work for.

You cannot care about a resume (because a resume is not a person) or a corporation (because although a corporation is person in the eyes of the law it has no soul). That is why the default way we hire is inhumane and beyond reform.

Caring about strangers is about the most soul-satisfying thing you can do; much better than going to another ball game with your kids. That is why I've taken my kids to my hiring events. (And I am glad to know that at least one job seeker at our Staffup Weekend brought a kid and everyone took turns babysitting.)

Even if you only care about the problem but not the people, once you get going on this approach you'll start caring about people because you cannot help yourself. There is something addictive about that, and addictive things tend to scale whether they are a good idea or not.

This one just happens to be a good idea.
