I don’t think it’s something difficult to reproduce using wordpress… I’ve seen only the homepage, but all I’ve seen is (in WP terms) a big “widgets enabled” header with some kind of “featured jquery plugin” showing their post_thumbnail in it, a sidebar on the right, showing authors with their gravatar and a bit of info, under that a simple twitter widget to show latest tweets…
On the left the articles are displayed with their post_thumbnail, I presume the two that have a bigger image are posted under some special category that makes them “pop up” using css and a custom post_thumbnail_size…
Moving on there’s a footer with 4 areas, just using float:left in the css with some width applied should make the magic, then it’s simply a matter of making those 4 areas widget ready and adding (from left to right) a text widget, a list of authors (plugin or text widget), a list of events (text widget I suppose) and a subscribe form (subscribe2 plugin comes to mind)…
