Well, isn’t that an interesting one… Found this one off spoonfork. For a little further info, click this. Here’s an excerpt:
As most of you probably know, I’ve spent the last six months working at Friendster. I have not managed to release any code in that entire time. Finally on Friday we launched a platform rearchitecture based on loose-coupling, web standards, and a move from JSP (via Tomcat) to PHP. The website doesn’t look much different, but hopefully we can now stop being a byword for unacceptably poky site performance. I also want to call out our first new user-facing feature in a long time, Friends in Common (upper left corner of your friends’ profiles). Try it out and let me know what you think.
PHP 1-0 JSP.
