Everyone on HN isn't enough to have an impact. And telling friends and family isn't good enough because changing default behaviors is very difficult in practice and they would listen do you, but ultimately keep doing what they're doing.

I agree, but when my 70 yo mother was visiting last month I watched her look something up on her ipad and she typed in "duckduckgo.com" to do it! I was amazed and asked how she learned to do that. Apparently, she learned it from me! She said she thinks it gives better results. Then I set it to her default search engine so she wouldn't have to type it.
