O’Nolan, a former WordPress project lead himself , opines
that WordPress has grown up and is no longer really about
blogs anymore. It’s become a full-fledged content
management system, burdened with a lot of unnecessary
complexity for those that are just looking to manage a
blog.
WP is nothing close to a full-fledged content management system, and if it's burdened by anything, it's all the leftover cruft from the days when it was just about blogging.I use WP every day and I'm really grateful it exists. But from my perspective, the problem is not "WP is so great at content management we need to develop something just about blogging". The problem is "Lots of people have cleverly managed to hack WP into running as a general purpose CMS because there's such a wealth of support, knowledge and extensability surrounding it".
I'be be much more interested in a new modern, flexible CMS built for that purpose from the ground up than I am about a new blogging software.
