A lot has been said about the drawbacks of hamburger menus, and we've been seeing a lot of mobile apps moving away from this navigation model in favor of a nav bar (recent example).
In general, I'm in agreement with the thesis behind these arguments, but I'm curious why we haven't seen this trend on the mobile web. Is it just a matter of designers concerned about bucking convention (or finding via AB testing/screen recordings that doing so confuses users)? Are the more complex navigation structure of large websites less appropriate for the nav bar treatment? (I'm not completely convinced this problem is too hard to solve.)
If anyone has examples of content-heavy sites (ecommerce, journalism) that have successfully used an alternative to the hamburger navigation, I'd love to see them. I've seen some that use menus that supplement the hamburger navigation (Sephora and Keep.com are two that come to mind), but I'm pretty sure I've yet to see a site where the hamburger menu is completely supplanted.
