The physical vs. online privacy shift is interesting to me as someone who was growing up during the rise of the personal use of the internet. In those times we were warned never to post any personal information or names online. But our physical house addresses and phone numbers were all in the whitepages.

Now we post so much personal info online, but whitepages are no longer a thing (although some voter registration systems have that data publicly available, or other for-profit companies that sell our scraped data)
