I'm developing a website that's almost ready for release. I'm a coder, not a designer, and my designer doesn't code. So I've been basically implementing her designs myself. Everything is finally perfect, and has been tested on various browsers and mobile devices, and it all looks good...except one thing.
It looks great on mobile devices in landscape mode, but is too small in portrait mode. So my question is this: how important is it to get it working in portrait mode? I figure most users, when they see the small page, will instinctively rotate their device, but then I remembered that some people lock their orientation. So how frequently do people lock their orientation to portrait rather than landscape, and what are the reasons they might do so? These are things I need to consider before deciding if it's worth the trouble to make things work in portrait mode here.
