I currently work for a company that recently jumped into the top 200 trafficked sites worldwide. The current site is driven by a poorly implemented PHP solution. I currently am not responsible for the site, but would like to convince the CTO to begin the conversion to J2EE. I would like to try and gather some data to back up my argument. Does anyone know where I can access data showing what technologies high volume sites are using? Also, any other information that would help my case would be appreciated.
