Practicing yoga is the only requirement to be a yogi. Hacking is much the same way. We all share similar goals but our practices are always intensely personal. If you're practiced enough you know that what you consider important and what you consider progress continuously changes. Thus we don't judge someone else or their practice but appreciate the opportunity to practice with them. Without question both Zed Shaw and _why have hacked. I think it's important to appreciate many qualities of both without needing to apply labels to either.
Namaste
