It's not arrogance.... it's just easier to do this for me. It's a wordpress blog without blogging(posts). All content is embedded from external sources (facebook and twitter) so if the host goes offline, cloudflare takes over and the snapshot will be enough to reach my goal because the information is all external.
I'm using plugins that can be added to the sidebar, so the "main" column is also a (inner)sidebar and not a page. By using a fixed width for the sidebars, I was able to 'hide' the real wordpress main page(which is empty) because I don't need it.
When I would choose a fluid layout (an option in my theme), the (hidden) wordpress main page would adjust to the resolution so it would be visible on high res displays, reveiling an empty page which I don't want of course.
I've checked the page on my Iphone4s and it shows the complete page, regardless of what resolution the webpage is so I can doubleclick the column to focus on it and the selected column will be zoomed in to match my small screen.
I've checked it on a little android phone of my gf (sony x10 MINI) and it does the same so with all respect, I don't see any disadvantage nowadays to use a fixed layout on any resolution.
