Wow. Nice site. You put mine to shame. Suddenly I feel motivated to make some improvements.
Oh wait, my boss is a design turtle.

Nice job on showing what Joomla can do. Here are my suggestions:
As you scroll down the web page, the left and right sidebar seem to become less defined, and the modules/content in them cease to be continously aligned. You might want to look into some way to properly align the elements. If you include (occasionally) a block style element (look at my webpage , note the news flashes thing, thats one of the few changes I was able to make with my boss's approval

) you will redefine the column as a column and give the website a more stable feel. You could also bring the left/right "fade" lines down a little more. The right Sun Microsystems ad that I see actually accomplishes this because it appears to span the width of the column , even with its negative space- the square ad on the left, however, doesn't. You could embed that add in a block-bevel thing and it might look nicer, or make one of those left elements a block type thing. If you made the CIO's online thing in a "ticker type" format, (a smaller box with a scrolling dynamic list), that would look cool and accomplish this objective. Obviously you don't want too much action on the webpage (avoid the dancing hamster effect) but there can be one or two active elements per "browsing window" of approx. 1200x800.
The blue color scheme is a good choice.
See if you can move:
News & Noteworthy Archive
Past News Items From Reuters
To the left column, you should have that quick comment thing be the center of the show in the footer.
Anyway, I've gotta move on to other things, good luck with your venture, ill bookmark your site and look at it here and there even though im not an IT guy technically
