Edit: Super power here is setting up a 1Password Identity (or whichever tool you use, hell, even a snippet) to auto fill junk email in when signing up for stuff vs not-junk email. I have three identities. One for work, one for personal, one for junk. Makes this stuff super easy and fast.
For example, see: https://www.npr.org/sections/money/2012/07/13/156737801/the-...
Other people do value their time, therefore it's not free for them.
Average person on here views those hours as billable if they were to do it themselves, when they make decisions about what to do, or alternatives (opportunity cost).
Maybe he should charge them consulting rates for this PDF (and not take their -- correction: an -- email. The horror).
It's only because this is HN that it's even a discussion.
I would rather use the term opportunity cost.
