We have had younger users ask questions in the past. It's great to see children show enthusiasm for space exploration. There has been at least one meta discussion in the past about creating a tag for questions written by or for an audience of children. (Despite having many upvotes, that request was denied, but apparently because the tag was confusing.)
About an hour ago, a 12 year old posted a question. I added a new tag called written-for-kids to it. The intent is that answers should be written for a younger audience. The tag description states
This question and its answers should be written for a younger audience: children under the age of 16.
That age was arbitrarily chosen, but a reasonable cutoff for more sophisticated questions and answers.
This raises several points for discussion:
First, sorry about doing this without prior discussion. Are we okay with going ahead with this idea?
The tag is intended for questions asked by users self-identifying as younger. Should older users also be allowed to ask such questions, as long as the answers are written for younger readers? Should there be a limit (number of questions, reputation limit, daily rate) to prevent abuse?
Should duplicates (but one only) of standard questions be allowed, so they can be answered at a more basic level? Or perhaps allow simpler answers in the original that are tagged at the top written-for-kids?
Are there any other types of questions that we normally would not allow, but would be okay with this tag?
Are there types of questions that would normally be allowed, but not allowed with this tag? (For example, most technical questions would not be asked by a child and are therefore inappropriate for the tag.)
What should the guidance be for answers? To what age level should they be written? Should references be mandatory, encouraged, or optional?
Are there any questions we would want to retroactively apply this tag?
Are there frequently asked questions that we want to establish a standard question and answer for?
