Wordpress template for handling aggregated social media

Hi guys,
Im looking to provide a wordpress website that is centred around social media campaigns.
There will be a number of authors, each having twitter, youtube, blogs etc… The new wordpress site should somehow aggregate this content and display it all on one website.
Ive been hunting round for a template and/or widgets that will provide this sort of functionality, but had no success. :confused: Can anyone recommend a template or plugins that would lend themselves well to this sort of website?
