What about the page that provides critical information but only receives a fraction of the hits than a page that is pure fluff. Avoid the quality vs quantity issue. Don't use marquees. You are already presenting information on your page. If the marquee information is important, then put it on the page.
Marquees render the dialogue box unusable.
I like seeing where a URL is pointing, or how large a graphic file is that is coming in, or what a button definition is for the tools that I am using. Avoid frames for the top level pages. If you are going to use tables to simulate frames, be careful defining the full page width. If you define at 800 pixels and the visitor's monitor is set at 600, there is a region of the page that can only be viewed by scrolling right.
