As an outsider to scaling issues, what strikes me about SoundCloud's struggles with shedding their Rails past is how similar their problems sound to Twitter's problems. Granted, a microblogging service has a different set of concerns than an audio delivery service, but the pain is the same. Going out on a limb, perhaps this similarity contributes to the reasoning for the Twitter/SoundCloud acquisition rumors: more exciting problems for Twitter engineers to solve now that they've tamed their own beast? Or to put the theory in a business light, Twitter engineering leadership may have confidence they can architect SoundCloud better than the SoundCloud team has done.
