Yes, maybe there is a lesson here for the future of the Web, Internet, and media content: Some people really like actual information instead of something extracted from the techniques of formula fiction entertainment.
That is, there is an audience, so far not very well served, for good information.
Soooo, HN can attract people who want good information even if they run BBQ restaurants and don't read about neural networks, the latest microprocessors, or the question of P versus NP. Sooo, we have some evidence that some of the audience so wants good information that they are willing to jump over a high fence into Techy-Land with issues of cache concurrency in multicore processors or distributed databases to get their information.
Part of the future of the Internet, then, is (A) generating such information and (B) helping people find from all that information what they like.
Just because someone owns a business in an industry does not mean they themselves work in that industry. It's quite possible that he is (or was) in the tech industry in addition to owning a restaurant...
I’m always so curious when I see the sheer diversity in backgrounds and interests on HN, especially when not directly related to tech.
