I'm not quite sure what it is, I have heard it be associated with a lot of forum softwares, blogs, and everything else out there.
Used it, liked it for awhile, then just stopped using it. No idea why. I got tired of it and it was really confusing on how to do things, and so I just stopped. The main problem was that no matter how many times you modified Joomla, it still looked like Joomla. It's not like you could make it look much different than what you already get.
yeah i agree wiht that... Most times you wouldn want to know whats in the code... especially if you got it from a 3rd party site
well it's really easy to use. it's true that you can customize it, but it has numerous templates from which you can choose the one that fits your website.
I tried it once but it is far more complicated than wordpress and was beyond my reach So shifted back to wordpress
I admin a heavily modified Joomla site for a client of mine and it is decent, but for most projects I usually have a custom CMS built that fits the clients needs exactly.
