What is the market share of Wordpress software among professional bloggers?

I'm talking about the Wordpress software and NOT the free web-based Wordpress service. Thanks, everybody!

1. That is hard to provide you with the exact specific numerical figure that you may be looking for. But one thing that is quite clear is that most professional bloggers (hey, I used most, not all) tend to use Wordpresss software as opposed to other platforms. A good place to visit for more details is Technorati top 100 blogs and you can be able to work up the list and discover what software they use to run their blogs.
