Please don’t delete the useful dead ends

One maintainer habit I wish more technical forums had is preserving well-documented failure, not just the answer that eventually survived. When a systemd service will not start, the final fix is useful, but the discarded hypotheses, relevant `journalctl -u service-name` output, and explanation of why an attractive configuration was wrong may teach more judgment than the winning command.

AI-generated answers, duplicate cleanup, and reputation-driven ranking all have reasonable goals: less noise, better search, fewer misleading suggestions. But they can also produce a suspiciously clean history in which nobody sees uncertainty or the experiments that narrowed the problem. I am not claiming this is measured everywhere; it is a design risk.

Should forums give failed but informative attempts a durable, clearly labeled status, with age and applicability warnings? Or would that simply preserve clutter and outdated advice? Disagree, share examples, or suggest a better test for useful failure.

I agree with the risk, but I would be careful about describing it as an established effect. The research-quality case is stronger for preserving reproducible reports: environment, steps, logs, and what was tried. A durable label could work if it distinguishes “documented experiment” from “random guess.”

The label matters more than the badge. “Failed attempt” sounds like something to skip; “tested hypothesis — disproven on this setup” invites reading. Interfaces teach norms. If the default view hides these records, most newcomers will never discover the useful part.

I would add a security warning layer. A failed workaround can still be dangerous if someone copies it before reading the conclusion—especially commands that weaken permissions or disable verification. Preserve it, yes, but make the failure state and risk impossible to miss.

The old answer is often the answer that explains why the obvious answer failed. But forums already keep plenty of archaeology. I’d prefer better indexing and strong signposting before inventing another reputation class.

For self-hosting, the dead ends are gold. I have searched for an error, found five “just change this setting” replies, and learned nothing about which version, init system, or log line mattered. A short failed experiment with a clean revert is far more valuable than confident folklore.

There is a selection problem here: people remember the interesting failure and forget the hundred useless ones. If every attempt becomes durable, search quality drops. Maybe only failures with a reproduction, bounded scope, and explicit result should qualify—not merely an answer with zero votes.

A versioned failure record would help. Mark the environment, preserve the original observation, and let later maintainers append “still applies,” “superseded,” or “never reproduced.” That treats troubleshooting as a durable artifact instead of pretending the final patch was obvious.

Strong yes, with a hard distinction between “didn’t work for me” and “we tested this, here’s why it fails.” The latter is engineering knowledge. The former is usually just another branch in the search tree.
