While reading this post from ReadWriteWeb (@rww), I had a thought.
Error message pages should be wikis.
Applying crowdsourcing to error message pages creates a dynamic forum that could benefit both users and developers.
Instead of request-response support through email or trouble tickets, i.e. asking for steps to reproduce, environment, etc. that information could be collected immediately on the error page itself.
Plus, the historical record of other users who hit the same issue and perhaps resolved it, could benefit people seeing the same issue for the first time.
And if the error page provided unhelpful text, a wiki could resolve that, even mitigate the anger many people feel toward software failure by providing a burn book.
This has promise. Must noodle it.
