Ever seen a site like viralbabble.com, web20.originalsignal.com, sportsnipe, etc?

Basically these sites are one page and they pull in a bunch of headlines via RSS feeds. Then each feed gets its own column on the site.

I've built some sites that pull in multiple feeds, but I've always combined them into one list using an array in SimplePie Multifeed. I don't have a clue how I would keep them separate yet have them all displayed on one page (like the sites listed above do.)

Has anyone done this with the help of Carp, Magpie, Simplepie, etc?? (I'm not skilled enough to do a lot of programming myself...)
