Well since the question asked for one website, I'd say Google News. It gets me quickly caught up with what's what in the world.
OTOH, for a longer read with topics I'm interested in, I hit Zite on my iPad or on my Android phone. I've got Zite configured with my favorite subjects, and now I'm fairly comfortable that I'm hitting 80-90% of the most interesting articles/goings-on without having to hit dozens of feeds or sites.
