I use password composer. (<a href="http://www.xs4all.nl/~jlpoutre/BoT/Javascript/PasswordComposer" rel="nofollow">http://www.xs4all.nl/~jlpoutre/BoT/Javascript/PasswordCompos...</a>)<p>But the point is, most people don't care about reusing passwords. Even most people on HN.<p>This is just another example of us techies getting distracted by things <i>we</i> care about. The goal is to build something people will use. Privacy just doesn't matter.
