I gave WordPress a try for my new Dorset DJ website but I found it too simple personally coming from Dreamweaver myself.

I wasted about 3 days trying to adjust a theme to be as I wanted it before I decided to go back to Dreamweaver.
It's quite a lot more restrictive than I thought it'd be, easy enough to install on your web host. Have a little play with it and see how you feel though!

Maybe I'm being a little pedantic but how would one go about adjusting the breakpoints for navigation bar (for example) in a responsive theme on WordPress so that the navigation always fills the page until it can no longer without ever taking up 2 lines?
