Frankly, I think that this is a terrible layout!
I can get Tech news anywhere - it should not be the main focus of your website. I come to Toms Hardware for reviews and other articles on the newest components, devices, servers, technologies, etc.. And honestly, relying on tooltips for article summaries is a poor choice. When I view articles, getting a quick sentence or two helps me determine whether I actually want to continue reading.
Further, I question why there is such a focus on the live feed from the Forum. The content that YOU create should be more important than what noobs and trolls post into the forum. Looking at the live feed, one question that appears on your home page is "WHAT IS YOUR FAVE COLOR FOR A CAR?" --- REALLY? This deserves space on your home page?
Focus on your content, please! Tech news is important, but original content and opinion should be the focus on your homepage, not mindless drivel streaming out of your forums.
