I love clean sheets.
And now I love cascading sheets.
Having an organizing tool like cascading sheets is like having a girl's closet instead of a boy's. A boy is lucky if he HAS a sock drawer: a girl not only has a sock drawer, she may have them color coded.
Cascading Sheets are like that: you may send out hundreds of RSS scouts, but if they all come on back in to the campfire to let you know what they found at once, its as good as not having any information at all.
Those of us studying the results of the stimulus program ran into that problem on the government's site: plenty of info, but no real way to access a refinement of the massive number of numbers and documents flowing into the site.
When you have traffic in that kind of a cluster, you need a way first to route it, then to organize it before it's usable: here come the CSS troops.
With a cascading, visual organizer you can, even with multiple search engines, make uniform the VISUAL organization necessary: fonts, layouts (margins, indentations, etc.) colors....you may have thousands of scouts but when they come back in to report for duty they will be lined up, in appropriate uniforms and easily distinguishable for use.
