Wow. I liked it a lot. Very clean mockup. Looks like there's lot of positive reviews in this forum. So that's a good start.
However, I noticed you didn't include "positive" and "negative" on each articles/news? Don't forget to include that.
Also, IMO, the header and footer.... not too sure about that. I think it'll be OK!
I think I just found out yesterday that AppleInsider just launched new mobile site for iPhone/iPod Touch. It's not bad but a bit laggy when the menu hide/show.
Maybe you can design mobile version (just one page) and see what it looks like? Keep up the good work!
ARN, I think you should re-consider this if you're going to re-vamp your site and MAKE SURE there is no more table layout!
