If there is one thing I admire about Matthew Weier O'Phinney, it's the amount of passion he puts into his work. He perceived concerns about best practices for developing models when using Zend Framework and took the time to write up three blog posts that detail his own experiences and recommendations. When I began actively using ZF on a daily basis in early 2008, I had questions similar to those that the aforementioned blog posts are intended to address.
