How would that work for someone who has a job where their code is proprietary and, in their spare time, they like gardening? Or do you just automatically exclude folks who don't develop their own sites with 1000s of users?
Ugh, why does everyone miss the point? If they can't show me any code, I'll talk to them and see if they know what they're talking about. I've found that you can tell whether or not someone is technically competent from a five-minute chat.
