The "First Posts" queue is all about helping a new user see how things work here. As such there are only really 3 options for outcomes:
- The answer is great and has no issues at all:
- There are some content or formatting issues:
- There are major issues with the answer or the user is doing something wrong:
- leave a comment telling the user what is wrong
Higher rep users have a 4th option.
- I hate every possible thing about this and want it to die in the pits of Hull
In this case the answer needed something done to it. Ether the cryptic phrase "restart server after change in setting.py" needed explaining or the contents of the link needed to be used to support a proper answer. Either doing the edit or asking the user to do it would have probably passed the review.
There's no point in flagging as low quality in the first posts queue as you are not telling the user what the problem with their post is.
Each review queue has a philosophy, which can be gleaned by looking at what powers you have available in each queue.
The site isn't just about making good stuff and weeding out the bad, we educate people. Sometimes education isn't just about taking their bad stuff away, it's about telling them why it is bad.
