Show HN: Limit your web time and stay focused with self closing browser tabs

As clean as possible for who? You've probably devoted many hours to thinking about the tool. I'll probably give your webpage two or three minutes of my time. If you are very very very lucky, someone else might click on a link to your page. That person probably won't spend much time trying to figure out what it is and if they can't their answer to "should I care?" will be null because they won't bother asking that question without knowing what it is.

Which of your ideas is more important, being as clean as possible or people using the tool? To me, the hard thing about good design -- and part of what makes it distinguishable from art -- is that good design is designed for someone other than the designer.
