Tab display collecting all the questions with an active bounty. Git yer shotguns ready.
The Bountied tab lists all those questions with an active and open bounty. They are listed in bounty time order: questions with bounties expiring closer to now appear top most. The longer the bounty has to live, the lower down it will show.
If you're searching for a post and were lost on the Bountied tab, your results may be zero or very close to nothing. Change your tab view to correct this misalignment of the Stack Exchange search engine results universe.
