I can be such a ****! Sorry I misread your post.
I really think if you are happy with wordpress then you should stick with it for this reason:
We all know that our most valuable attribute is time. Time is money. When we are building sites and trying to make those clicks turn into sign ups it can seem like we never have enough time to get all the stuff done that we want to.
I know when I first started it always seemed like I had so much to do and so little time.
I’ve seen some great wordpress sites and sometimes I look at a site and go “wow!, they did THAT with wordpress!”
Learning Joomla is something I would discourage you from because it takes so much time to learn. With wordpress you get going pretty much straight away but with Joomla even if you use the rocket theme launchers like I do there is still a hell of a lot of work to be done to get it looking like a site.
I think the main advantage of Joomla is that with the menu and module system you can create sections of a site that are totally focused on the niche target.
For example you can create a poker section that has all of its own banners and modules totally different from the casino section etc. Which I don’t think you can do with wordpress. Maybe you can but it takes a lot of work.
For small niche sites and general day to day sites wordpress beats Joomla hands down but for multi section/author sites Joomla is much more powerful and flexible.
I like Joomla and rockettheme means you can have a nice looking site right out of the box but that’s only the start of a can of worms.
For example getting Jquery and mootools javascript libraries to work together on a new site took me three days to figure out with support from Jreviews and the template people.
When you want to do more complex stuff like run some nice reviews software etc then it can be hard to do with all the different versions and conflicts unless you have access to a good programmer which lets face it most of us don’t.
Those lost three days could have produced twelve to fifteen articles of high quality content published quickly with wordpress.
My advice is to stick with what you know because it is a lot more productive than what you don’t.
When you are making enough money with all the wordpress sites you can afford to **** around with Joomla and see what you can do with it. And afford to pay someone who knows PHP to sort out all the inevitable problems.
