Due to the nature of my work I get into contact with a lot of people who are doing web development and design. I had a very interesting discussion with someone over the phone a week ago and he mentioned that many people in the US actually use WordPress to develop their sites.
I tried WordPress around 3 years ago and wasn't impressed much and ever since then I have been using Joomla instead. I find it to be easy and although it is open source, the support has been awesome so far.
I have no idea if anybody else on ODN have experience in Content Management Systems, but would like to hear your take on it.
Select which CMS you prefer and support why you like it. I list only those I am most familiar with.
