In the last days I stumbled upon two first posts in the review queue I considered bad quality, one being a (shopping-list) question and the other a (link-only) answer. My approach was the following:
In the question I left behind a comment welcoming the new user and explaining whats wrong with his question. I invited her/him to edit the question to make it better. Then I voted to close the question.
With the answer, I just left behind the comment, similar to the one below the question.
I am unsure about especially two points:
Should I immediately vote for close when the post is bad, or wait for the user to correct it? Probably the post then will have disappeared from the review queue and might be difficult to catch.
Should I edit them myself to make them better? I like it more to leave that to the user themself - it allows them to learn about it, and I don´t know their intentions.
Do you have any other suggestions how I could improve this? How should the reaction to low-quality first posts look like in your opinion?
