Opposite to the 'Hot' tab, the 'Cold' tab would show questions with the least views, answers and votes for the past week, allowing them to get a little attention.
Whether that attention be answers, general cleanup/editing or even the unfortunate close vote for a few unsalvagable questions, better for them to be noticed then dissappearing into the void of untouched questions to be eventually purged from the system.
Thoughts?
