I've come to the belief that crypto and security are a 'feature' and never a product.
As important as these issues are - I find that businesses and consumers don't often opt for these things as a primary choice except in specific circumstances, or for specific consumers with specific needs.
The fact is - I think - most people don't care. Even most startups don't care that much. If their conversations are 'reasonably secure' then they're good with it.
I think HN readers are way to one side on this issue - we care a lot about it. I think our views are different from that of most people.
This could change but I think we're still in this mode.
