Abandoned the Rails
So it will be happened.
Twitter Said To Be Abandoning Ruby on RailsWe’re hearing this from multiple sources: After nearly two years of high profile scaling problems, Twitter is planning to abandon Ruby on Rails as their web framework and start from scratch with PHP or Java (another solution is to stick with the Ruby language and move away from the Rails framework).
Python or PHP? :-)

PHP lah… hihihi ###kompor terusss### :D
Seriously – bukannya Python juga adalah masalah performa untuk load besar? Rasanya saya pernah lihat komparasi antara berbagai web platform, kalau tidak salah Ruby & Python, dari sisi performa, termasuk bottom performers.
