Why use WordPress?

WordPress

As those who know me will testify, I have not always been the biggest fan of Content Mangment Systems (CMS). In my time I have worked on a few large commercial systems and that experience has left me a little cynical. I still come to each new system with a touch of healthy sceptism. However, I have now been using Wordpress, for my own and client sites, since the release of 3.0 back in June last year (June 2010). Why did I make the jump?
