> For example, when developers need to ask their teammates questions, they tend to default to the tools that they’re already using daily: namely, chat and email. But those tools have their own problems. Chat is ephemeral and tough to search, and email is inherently limited to the people included or copied in. Both tools put a lot of strain on the few developers at a company who know the answer to a given question, and neither method excels at storage and recall.
