I recently blew away my vertical main navigation menu in favour of the horizontal sucker you see above. When I built it, it was important to me that it not wrap on a screen resolution of 800 x 600. I've always believed I should build for these people and ensure it still behaves properly for those who are higher.
Today I felt it was time to promote the Smells Like Sour Database to the main menu, but again I checked to ensure it remained as a single line when viewed by the 800 x 600 folk. It does and that's why you now see SLS on the menu above.
Why do I care so much about the 800 x 600 crowd? They're a dwindling bunch and I suspect the people with these tiny monitors and high resolution are the same people who don't know what a blog is and confuse email addresses with URIs. In fact, I seriously doubt more than a handful of visitors to this site have their screen resolution set to 800 x 600 and that's probably because they're unemployed slackers who can't afford to upgrade their eight year old 14 inch CRT. Bless their little hearts.
I'm looking forward to the day we think of the 1024 x 768 set the same way we now view the 800 x 600 people. I've been 1280 x 1024 for quite some time and I'm not looking back. 800 x 600 people be damned. You're either with us, or against us.
