Do We Still Have To Support All Browsers?

Is anybody still using v4 browsers?

• ESPN.COM says 98.4% of its visitors use standards-compliant browsers
• Less than 10% of visitors to UW sites use pre-v5 browsers

Do standards-based pages work for old browsers?

• Pre-v5 browsers have incomplete CSS implementations
• Pages may not look as nice, but should be still be usable

Will people object?

• Some may object
• Upgrading to newer browsers is easy and free
