Perhaps instead of being annoyed, you could try to understand why people are sighing. Many of them will have lost out on a job they were qualified to do because of bullshit interviewing practices like this one. It has a real effect on them. It's not a trivial issue.

No one here has claimed to have it all figured out, nor are the majority of comments an implication of that. We're all just saying we have one thing figured out: whiteboard interviews are terrible, alienating, unrealistic, antiquated tools for hiring.
Your profile says you're a CTO, and you should know that research increasingly shows that people don't quit jobs, they quit bosses. If you want to be the kind of boss that programmers want to work for, you should be more open to understanding why the vast majority of us feel strongly about a topic like this instead of calling us obnoxious.
If you yourself are not a programmer, I'm not sure why you're weighing in on this at all.
