I would align the navigation (Homepage and About) to something--either right aligned to the search box or inline with Search and Latest Articles. There's no real focal point. My eyes aren't sure where they want to go. You need to visually tell me where to go. Nice colours and nice simple layout.
the menu bar at the top isnt working and you need to add much more keyworded content. Then yiou can just let it run itself as a minisite via adsense
the text in the header is very jaggedy for me in firefox 3.5xx. i like the colours and simple layout but a nice image would massively improve the site. also perhaps centre the header to the middle of the blue bar rather then just under the centre. . the blue bar at the bottom of the page doesn't extend all the way on my 20" monitor, it stops about an inch from the bottom leaving a white space
I haven't open the page because Chrome has shown me a malware alert! Some of components from elpotrero.com.ar used on your website contain malware or viruses.
Yea...just saw that... I CAN'T BELIEVE THIS SHIT. I had to deal with this malware shit like 2 months ago and now it's back. I have no clue how it continues to get on to my PC and access my domains.
