After talking recently about the pros and cons of building your own CMS with a colleague, and especially the time that goes into building one. Is it really worth it?

Now I must state that as primarily a designer, the developer role doesn’t come as easy to me. The main reason I use WordPress on this blog is that is was so quick and easy to set up.

However with speed being a major factor with mobile web, Google rankings and the complexity of WordPress, I’m pretty sure that a billy-basic CMS would load a lot quicker. But do people really care?

Reality probably means that I’ll stick with WordPress, upgrade to v3 and be able to write blog posts like I am now on my iPhone.

So, have you ever written your own CMS, or wanted to, or do you think that off-the-shelf systems are more than capable?
