I think maybe you were thinking of a different site link, because this is the first time we&#x27;ve been on HackerNews to my knowledge, and our shortest sessions are 15 minutes, and they never loop. If I&#x27;m wrong then really sorry about a bad experience, must have been a bug. Give it another shot if you have a moment :)<p>Lots of science to this.
