Okay I'll take you at your word for it until I see it in place. Maybe I'm just too "Old School" to envision it as I see that stuff more like a BLOB of ugly coding.

I've been to a few sites that have stuff like it and it just doesn't do much for me.

Gizmo, you said you have some sites that use it? Care to share a link so that I can see how you're using it ?
