If the folks over at WordPress are to be believed (and they seem suitably trustworthy sorts), it now ‘powers’ over a fifth of the internet.
It’s easy to see why: on WordPress.com, you can rapidly create a new blog entirely for free, with a reasonable amount of customisation; alternatively, most web hosts provide WordPress as a free single-click install, and more info on what’s possible there can be found at WordPress.org.
Newcomers might find WordPress a touch bewildering initially, but it’s the best free option for anyone wanting a great mix of power, customisation and usability.
