This is not a question about old orphaned questions.
Its about old unorphaned questions like: Does ruby have real multithreading?
To remain correct this question will need constant updating. An absolutely wrong answer is marked correct and receives free advertising by being green and showing up first. There are 3 additional answers that add no value to the discussion and this is the number one result for googling "ruby real multithreading".
This question cannot be asked again, as it will be marked a dupe, there is no motivation to keep it up to date, so it's bound to get out of date.
Do we have some sort of responsibility to clean up this mess? Should there be some sort of incentive to help maintain this knowledge? Should ownership be revoked from the original asker?
I just noticed this is actually an abandoned question. The user no longer uses Stack Overflow. Nonetheless I'm sure I could dig up similar questions by users who have not abandoned the site.
