Ask HN: Is there a better alternative to email?

Email, chat and almost everything else is just text. All text is searchable. I think what you really want is something that searches email and chat systems for relevant topics and maps them together for your org highlighting things people are talking about. The search system would have to be aware of identities to avoid leaking sensitive information and causing corporate security incidents.

Become an email completionist, and send emails to other people as if they should also be email completionists.

Pardon me. What is an email completionist?

Someone who reads every email, or at least looks at the subject long enough to do something with it (delete, move, ...) and don't leave unread emails in their inbox

Yes. I call it, “Talking In Real Life” (TM).

Email Is mostly for work, government paperwork, and other professional setups even if we meet in person.
