Hello guys, I wanted to share with you our work at pearltrees.com. I'm quite new on the forum and I'll be happy to share with you my feedback on Zend Framework scalability, Flex 3 memory issues & Firefox extension programing Basically pearltrees helps you to organize your web, guide your friends and readers through your Web and let yourself be guided through the Web. For instance, here is a map created by my friend about his flash experience (performance, security, wmode issues, ...). Thanks for the review. Nicolas.
