on-topic: I believe each CMS has its own advantages and disadvantages
I think relatively new webmasters are kind of forced down the WordPress trail. I felt compelled to post about my theory of the WordPress Cult developing. This phenomenon must irritate developers of new innovative ways to create web sites.
The best CMS will depend on what kind of website you are looking to create. I don't think that it is a case of one solution fits all situations since sites are so diverse such as Blogs, Forums, E-commerce, Web 2.0, business home-page etc.
