I've been posting a lot about the Zend Framework recently. That's because I've been using it in building a new version of my wishlist site. The new site is called One Wishlist and is at onewishlist.net. It uses version 0.7 of the Zend Framework. I'll try moving it to version 0.8 soon.
He's still updating things as he moves the content and site's functionality over to the Framework, but seems to have found the transition relatively painless. Check out onewishlist.net for yet another example of a site implementing the Zend Framework.
