Hey @melooo182. Thank you! You should visit it, so much to see there. And great vibe and seafood (and lamb, GOD!!)
Actually technically you don't lose anything with vertical! :) You only allocate more of the view in an up-down axis rather than a left-right axis. If it catches up, when it catches up, it'll be because fewer and fewer people view content on their computers and rather view it on their phones. And for the same reason that hit mobile games tend to have a vertical layout (you can play with one hand while holding on to your sandwich on a bus) vert video will fill that need. What's missing is the platform to share it, as people still (expect to) share and view a lot of content on the computers.
Essentially a mobile-only video platform, an Instagram/Vero for videos.
