Were navigation bars invented by lefties? Usability experts are always complaining about the fact that left-side navigation bars have become the ubiquitious standard across the web, because the hand (most) of us use to click our mouse with is on the right. So you have to slide awkwardly to get to stuff to click on.
With that in mind, as we redesign our own site (a seemingly endless project - arrgh!) I have tried to keep stuff I want people to click on to the right side.
This morning I noticed SRI.com
also does this on their home page, where everything they want you to click on or use (search, newsletter opt-in, links to articles, etc.) is on the right, and their big picture and mission statement stuff is on the left. Check it out for yourself and see if it's really easier, or more tempting to use.
