WordPress.com, 8th most visited website in the world
WordPress.com recently passed Yahoo! in Quantcast's rankings of the world's most trafficked websites. It's now number 8. What I find most interesting though, is that according to Matt Mullenweg this does not even count mapped domains, or sites on WordPress.com's servers that have their own domain instead of *.wordpress.com. Considering people with their own domain are likely some of their most engaged customers, it makes this ranking even more staggering to me.
