OK, I checked your site. It looks great. About your social media widget (on the left top) -- I think it is occupying a premium spot on the page... shouldn't be there, and it doesn't look too professional. Sorry to say that, my friend.
What I suggest is that you can put it in horizontal format, either just under every headline on the inner pages and on the right-hand side on the front page (You already have FB there, but you can also have twitter box too just below the FB box). See example (i) below:
Examples that I find more attractive are:
(i)
For front page:
Check how great the FB & Twitter boxes on the mid-right of the page is.
(ii)
For individual stories:
Code:
http://www.as.com/futbol/articulo/portavoz-deportivo-madrid-sera-mourinho/20110526dasdaiftb_13/Tes
The social media widget is just below the title as well as at the end of the story.
Looks quite professional. The particular newspaper page also has large FB & Twitter boxes on the rght sidebar... they remind the readers to take particular action. Social marketing/advertising is a must for every business, especially so for an online newspaper which needs to attract more and more readers and keep the existing ones.
Check this one:
Code:

See how they are keeping the social media bar fixed at the top of the screen and so the reader is never far away from the FB / Tw button... The div is aptly named -- User Actions, and the bar is named "User Bar". These guys understand the value of social networking / advertising / marketing, and could well be attracting a lot of targeted traffic from there. (Just saw their Twitter page -- they have great number of followers, and it also looks like they may be using something like TweetAttacts too... just a wild guess!

You can visit the above wen-page to check on more Spanish online newspaper and see how these are using the social media widgets on their sites. I think your own site's widget needs re-positioning for better effect. Try doing so and it may just prove very successful...
P.S.: Add a great professional bio to your Tw page. HTH.
