The different and inconsistent ways of navigating questions has always bothered me.
The home page has the following tabs
- active (questions that have recent activity)
- featured (questions with open bounties)
- hot ("hotness" algorithm looks at votes and activity)
- week (hottest this week)
- month (hottest this month)
On the Questions page, the tabs are
- faq (questions with the most links)
- votes (all-time most votes)
And there's a separate Unanswered page with tabs for my tags, newest, votes, and no answers.
If it were up to me, I would change it so that Questions is the home page, and it would have the following tabs.
I'd leave out "week" and "month"; I think a single "hot" tab is enough. I'd also remove "unanswered" because there's a separate page dedicated to unanswered questions.
