Question: What might be a good way to incentivize and/or promote the generation of definitions and wikis for undocumented or under-documented tags in this site?
I'm trying to think of perhaps some kind of campaign, or contest that would be both fun and helpful to the site.
There's no lack of users who are qualified, or of people who are naturally motivated to explain or define in helpful ways, but editing/improving tags hasn't been gamified (1, 2) the same way questions, answers, or even to some extent comments have been. There are badges, but not the near-instant gratification of the up-vote.
I'm wondering if some kind of community wiki for proposed definitions and wikis of say the top 20 or 50 popular yet undocumented tags might work, but that's just one idea, there may be better ways, perhaps a special tag-hat or even hat size mod?
What got me started writing this is the use of the j-2 tag on this question about $J_2$. While I'm guessing the tag was originally created to refer to the Rocketdyne J-2 engine, the OP likely started typing J or J2 in the tag selection box and it appeared like this:
and since there is no guidance either way is immediately provided, the tag was selected.
edit: The only tag currently on the question Could a gyrojet fire arm be used in space or has it? is space-gun and the problem here is that all the other questions are about a type of launch technology, not a firearm.
update: I've added a definition for this tag.
This reminded me of my earlier mea culpa meta question Easiest way to get a list of tags for which I've bee the first user? Algorithmically if possible!
