Bet the farm. Python or PHP?
fedecarg: 1. Based on content management: PHP. The biggest publishing site on the Web, Wordpress, uses it.2. Based on libraries: PHP. You have PECL, PEAR, ezComponent, Zend and many others. Whatever you need, it has it.3. Based on syntax: PHP. It's damn simple.4. Based on deployment: PHP. It's fast and painless.5. Based on execution model. PHP. mod_php, as an apache module, works and it’s scalable.6. Based on frameworks: PHP. Symfony and Zend Framework offer a modular, MVC, loosely-couple architecture. They not only provide a solid infrastructure, but also an extensive component library.7. Based on performance: Any, as long as you cache everything.Good luck!
