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. We do not encourage or support the use of 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.
Visitors 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 are being used. Marguees are not supported by all browsers. We do not encourage or support the use of frames. They are hard to create and maintain. Some visitors have strong opinions about their difficulty.
