I did that. I wouldn't mind changing my behavoir if there's a shared demand from the community to do so.
My reasoning so far has been that flags are a direct line to moderators and should mainly be used for cases that require ASAP intervenience or to execute actions only performable by moderators (eg:convert to comment, certification question answers, abusive spam, "social misconduct", ...).
While we're active, I do not believe we should become a bottleneck for certain actions that can be performed by the community itself. It's the community empowerment that we want to enlarge, not the moderation team or moderation time.
very low quality
and might need to be removed.> This question has severe formatting or content problems. This question
is unlikely to be salvageable through editing,
For low quality or incorrect answers I believe the first actions should primarily be to down vote and to comment or edit the answer. Not to delete or have it removed. It both contributes context to the question to know what are invalid approaches and educates the person providing the answer why they were wrong. That may even motivate them to pursue the real answer and yet update their answer.
In contrast: New questions, thank you comments or "did you fix this ?" answers do not contribute in anyway and should be removed as answers. By members of the community or moderators.
On community empowerment: Vote! support others for their contributions and keep in mind the privileges that come with reputation.
