Taxis are about 20% (rough estimate) cheaper than Uber in Japan. That, plus the already mentioned abundance and good quality of service of taxis in Japan (as well as the ease of booking one through phone/internet/mobile apps), leaves no real reason for most people to use Uber in my opinion.
I only criticized the title of the HN post, because it differs from what what was written in the article.
What followed was what I observed from my personal experiences, and I did not say that my personal experiences necessary reflect the state of the whole of Japan, nor vice versa, or prove this article false. These are just my personal observations, which happen to be the opposite of what was stated in the article.
Also, in addition to the very small sample set (3000 out of millions, even if we are just considering the age group mentioned), it also provides little to no detail of the sample selected (location, marital status etc). IMHO this is article seems sensationalist to me, or just bad journalism (no links to concrete sources or data).
I'm an engineer but my social circle is mostly made up of people who are not in web/tech, and from all kinds of industries (marketing, finance, medical, real-estate, business owners, etc). So this definitely does not (just) apply to the tech industry.
The title on HN is downright misleading. "... the Japan Family Planning Association interviewed 3,000 subjects, both male and female, about their sex lives."
Those aren't couples, they're just random men and women from what I understand this text.
Also, I have lived in Japan for the past 5 years and around me at least a lot of people are (very) sexually active, in fact, too active, or too casual usually. Most guys date multiple girls/have multiple sex friends, and even if they're married or in a relationship, many have sex partners other than their girlfriend/spouse.
Despite the misleading title, I wouldn't be surprised if couples reply that they haven't have sex with each other for the past month and were telling the truth (because they're too busy having sex with other partners).
So wouldn't the world be a better place for everyone if all the librarians in the world posted everything to a searchable quora/stackoverflow shared knowledge base? Instead of having knowledge fragmented and buried deep in places where people would have trouble finding.
Despite Google's global presence and all the smart and capable people they have, are still unable to offer international purchasing/shipping for one device almost one year after it's launch?
