Ask HN: Why Not Reply All?
Why isn't the default email reply behavior "reply all" vs just "reply to sender" as is the current convention?
That said, accidentally replying all with sensitive or embarrassing information is probably worse than accidentally sending a reply to one person instead of everyone, so it is a safer default, even if reply all is more common.
My job is not to read emails. I don't open a Gmail window with 200 unread CC'd responses and think that it's my duty to untangle that. I work on what I'm paid to do and wait until I'm told otherwise by my manager. The reason every single email client doesn't default to reply-all is because engineers are conspiring together underground to stop the unjust suffering and PIPs caused by missing the needle in the email haystack. Company-wide emails are the single point-of-failure that necessitate alternative communication platforms like Slack.
