What frameworks would you use to handle such an steep growth curve? Most startups I know of start of with rails or the like - and obviously they couldn't handle the strain. So what would you use?

WhatsApp was a pretty well known case for Erlang[1], given that I'd think Phoenix would be a great fit.

Erlang won't have helped twitter. Erlang has a very simple architecture, once they sent you a message and know it has reached your device, they no longer care about it. Twitter has to keep all the tweets, likes, retweets, show it all followers in real time. 100x more demanding than WhatsApp simple deliver and forget.
