Ask HN: What do you do for online privacy?

Two years ago, I submitted this: https://news.ycombinator.com/item?id=33558737 which turned up some interesting comments.

I thought I'd revisit this topic now that it's been almost two years.

# Applications, Operating Systems

Do you run specific browsers, and why? Do you have specific applications that you use to protect your privacy? Do you engage in any kind of hardening?

Do you run any specific kind of operating system (say, Windows, Mac, etc) and why? Does it matter to you personally whether you are tracked?

# Online Storage

For example, do you store files on cloud storage as-is? If so, what kind of criteria do you have for that? Do you encrypt all files before they go anywhere? Does AES128 or AES256 encryption provide reasonable protections?

# Social Media

Do you avoid or block social media? If so or if not, why?
