Related to Should we close outdated, abandoned questions?
It would be fantastic if we had a way to either manually or automatically flag a question as "abandoned." Many questions are migrated from Stack Overflow and the original poster never follows the question to update it, accept an answer, or otherwise engage in the community here.
Having so many abandoned questions raises our total number of "unanswered" questions, and many of these are bounced to the top of the "active questions" list by Community automatically.
