As other commenters have stated, I think that moving headers are distracting, and am quite frustrated that this has become such a pervasive pattern across the internet. I use the top portion of the viewport to track which line of text I am reading, and having a header flash back and forth makes this difficult. However, upon mentioning my frustration to a friend in the digital advertising business, she brought up the point that sticky headers save users from the carpal-tunnel inducing action of scrolling all the way to the top of a site in order to take an action (e.g. sign up for a service). We landed in the middle ground of debouncing sticky headers, i.e. the user should firmly establish their intent to view the top portion of a site by scrolling in that direction for at least one second. These thoughts aside, great work and thanks for contributing to the industry!
