Now that's idiotic. There needs to be a conversation before it can be used by more than one persion, and it likely needs to be used by many people as the result of conversation (and blog posts) before there is enough anecdotal evidence to warrant a scientific study.

Not to mention the fact that if it works for someone, it is by definition effective for that person, and worth noting for that person.

What's with the influx of HN'ers demanding scientific proof before any matter is discussed? Same debate happened over whether meditation was helpful.
