A theme for an online magazine (news, blogs)

Do you have a theme that works for an online magazine style (news, blogs, with multiple authors)?

The site I run is a multisite (with subsites dedicated to different languages while the main sites aggregates them all).

The themes I saw on WPMU so far appear to be tailored for other types of websites.

And, with none of the theme descriptions pointing my way and the poor internet connection I got, I couldn't narrow down to few and give them a try..

Related question: Are the themes and plugins developed by the same theme? (If so, I am assuming there may be an advantage to using themes from the same source I am getting plugins. If not,I can stick to my current theme from another source)
