The top page of Stack Overflow has the tabs Interesting and Hot, which I understand as 'the reverse order of time questioned,' and 'the reverse order of time of some activity on it', but when I filter the questions with a tag, the tab labels change to Newest and Active, which I understand to mean the same thing. Is my understanding correct? If so, why are the labels different? If there is no particular reason, I would prefer them to be unified.
These are indeed different from Newest and Active.
