Leading Russian design studio, like many other sites before them, just added on-scroll header. And I still don’t get it.
Do they imagine people regularly need to go to the completely different section of the site while being in the middle of the article? How often does it happen?
Then, even if somebody actually need this menu, are you sure people would be aware how to summon it? To scroll up and wait a second for it to appear? With no clear indication that it’s there, with no on-screen control to call it?
Or is it more likely for a visitor to accidentally scroll up or decide to go back a few sentences or take another look at the picture she just saw? And that innocent desire that is much more commonplace (as I imagine) triggers the whole hell of animations and activity nobody has asked for.
How does all this make sense again?
