About
This is one queue. Not one queue each: one queue, shared by everybody on the internet at the same time, moving at the same speed, towards the same door.
What actually happens
You take a number. The number is the next one out of a real counter, and nobody can be given a better one. The door lets people through at a fixed rate, so the wait you are shown is the arithmetic of how many people are genuinely in front of you, not a timer invented to make you stay.
When your turn comes, the server draws one of twenty endings. Sixty percent of the time it is something completely unremarkable. One percent of the time it is not. The draw happens on the server, after you arrive at the door, and nothing about it can be influenced from the browser.
What there is to win
Nothing. There is no prize, no money, no leaderboard position worth anything and nothing to buy. The Hall of Fame records rare endings because they are rare, not because they are valuable. The mystery is one sentence, found a fragment at a time, and when it is finished it will still be only a sentence.
Why it is built like this
Almost every pointless website is pointless on its own. This one is pointless together: the number in front of you belongs to a real person who is also waiting, the vote in a live event is counted across everybody standing in the line at that moment, and the counters are the real totals from the database rather than a number going up on a timer.
Nothing on this site is faked to look busier than it is. If the queue is empty, it says the queue is empty.
Who made it
Damian Chojna, in Poland, with a small server, a database, and more care than the subject deserves. The engravings and photographs used throughout are public domain or openly licensed, and are credited in the footer.
