Hello, hello, Discovered this forum last week. I have found several interesting topics, I'll be glad to spend more time around here. Little introduction. I'm working at pearltrees.com, a french 2.0 startup, as a developer. I'm playing with MySQL 5, Zend Framework 1.7, Flex 3 and Firefox extensions. I'll be happy to give my feedback on these technologies and their scalability. See ya around ! Nicolas
