As Ryan said, MODx is not for everyone. And, as you discovered, MODx isn’t like Nucleus, Wordpress, or any of the other blog software out there...you can’t use it like other blog-like applications without putting in some work into how it’s supposed to look and feel. I’ve tried Nucleus, Wordpress, Textpattern, and a slew of other popular blog and CMS apps. The reason why so many other blog apps are so easy to setup is because that’s more or less what they were built for. MODx isn’t like that...it isn’t built to provide specific functionality like a blog. Instead, it’s more of a framework to build things on top of. Sure, you can have a blog...but with MODx you are in completely control over how the blog is supposed to look and feel. Granted, other apps do the same...but the templating systems with other apps are significantly more sophisticated and require a little time to learn.
In a nutshell, we can expect MODx to be everything for everybody. The best we can do is provide a system that allows for the most flexibility and control, enabling web developers the freedom to do as they please. Not everyone will see it and MODx may not be the perfect fit for everyone. We understand that and we certainly won’t criticize anyone for believing in a different application. If you like Nucleus and feel that it’s the best fit for your needs then by all means stick with it. We won’t yell at ya.
