Here are two questions, both about adjectives being used as adverbs:
The former was asked in September, got one answer quickly and another in December (neither accepted), and was recently bumped to the home page. The latter was asked a day ago and summarily migrated to ELL.
I would have thought the second question was a good fit for the site; nevertheless, I'm not challenging the migration. The rules are what they are, and if the second question is unsuitable here, that's okay. I'm merely trying to get some clarity for myself regarding said rules: to understand what makes that query unsuitable, particularly when the first is worthy of being featured on the home page.
