Created another Joomla site, based on Joomla 1.6 this time. I decided to make it more of a real site and settled on Lean and Theory of Constraints as topics.
I'd say that if you're starting from scratch then 1.6 is the way to go but if you're looking to move a site currently on 1.5 to 1.6 resist it until you have to unless you you are a PHP expert or can hire one. Basically every extension will need to be re-written. That includes templates, modules, components and the whole kit and cabboodle. There's no backward compatibility at all that we've been able to find and even 1.5 native extensions aren't supported.
