Scenario: I come across a question that is poorly written, but is very new (like a few minutes old). If the question were older (as in an hour or so), I would submit a close-vote. However, since the question is very new, I like to give the OP a chance to improve the question, so I don't close-vote immediately. Instead, I comment on the question. In my comment I try to point out the issues with the question (e.g. "What do you mean by... ?"). Then, I keep the question open in a background tab and return to it later (like in 5 minutes or so).
However, sometimes I just don't feel like investing in a question like that, so I just abandon it. Which is why I had this idea. Imagine if you could set a reminder for a particular question. You would set the time (e.g. 30 minutes), and an optional message (e.g. "close-vote if question hasn't been improved").
Of course, if OP responds to my comment, I don't need the reminder. But from my experience, new users tend to ignore constructive comments, and just focus on getting a solution without having to invest any more time in explaining the issue.
So, with this feature, I could:
- comment on the question (pointing out how the question should be improved),
- set a reminder (30 minutes),
- if the OP responds to my comment, I get the notification; otherwise I get the reminder after the specified time.
So, what do you think?
