Twitter在应用程序开发期间使用哪个框架？
还是该构建没有任何框架？

通常,如何确定用于开发如此庞大的门户网站的框架是什么

Last week, [as of April 6, 2011] we launched a replacement for our Ruby-on-Rails front-end: a Java server we call Blender.

Twitter过去使用Ruby On Rails.这种环境有利于快速发展一个新站点. Java对于更成熟的应用程序来说往往更好.

从http://en.wikipedia.org/wiki/Ruby_on_Rails通过使用Google找到；)

Rails running on Matz’s Ruby Interpreter (the de facto reference interpreter for Ruby) had been criticized for issues with scalability.[25] These critics often mentioned various Twitter outages in 2007 and 2008, which spurred Twitter’s partial transition to Scala (which runs on the Java Virtual Machine) for their queuing system and other middleware.[26][27] The user interface aspects of the site continue to run Ruby on Rails.[28]

对于热门网站,我会尝试使用Google搜索来查找有关它们的信息.
