Knowledge that does not evaporate
The best sentence in last Thursday's chat is already gone. Not deleted — just unfindable, unowned, and impossible to point a new colleague at.
Documentador is the place that sentence should have been written. Spaces, pages, history, comments, watchers, attachments, PDF. When someone changes a runbook, you can restore the previous revision instead of reconstructing it from memory.
Answers is the other half: the question that is not quite a document yet. Voting, comments, domains. The fifth person with the same problem should find the thread, not reopen it.
Use Chat to decide. Use Documentador and Answers to keep the decision.
