I just posted a question to identify a feature of an Exidy Sorcerer's case I can't explain. Categorizing that kind of question seems hard, as it's not a computer or game to be identified, but a feature. Then again, it doesn't make much sense to add an identify-this-feature tag. Thus a more generic identify-this to cover all the less common identify-this type outside the big other categories would be helpful.
Why not make it a noun in line with other SE sites?
Certainly Identify this questions are on topic, after more than one confirmation question already here on meta...
Are identify this questions on topic?
So, I would say let's do it. Add identify-this.
