1. Because brainwidth is more precious than bandwidth: just because you must download it doesn't mean you have to read it.
2. Because it quietly personnalizes your computer and makes it strangely your own.
3. Because it's a beautiful idea.
4. Because ISPs can transfer the burden of filtering from server to client.
5. Because those mail client writers that have it will ruthlessly shame those that don't until everyone has it... shortly after Microsoft releases a browser that actually supports CSS2 without ugly floating hacks.
