In what way?
For if you are talking about the WP software, there are quite a few companies that make money money in one minute than I do all year using it.
There are so many RICH guys/gals using WP.
And for damn sure, there are the people who spend mega bucks to get developers, designers, etc. to set up their blogs and run them.
Now if you are talking those who go to wordpress and have one of those free blogs?
No more dummber and no richer than those who use blogger, tumblr, and other free blogs.
Like even here on netbuilders.
