I was illustrating another situation where the only viable path forward was an acquisition in response to the parent comment. I was not suggesting that there would be comparable hardware cost savings at Twitter. The comparison which I did make to Twitter was regarding advertising delivery where I said "Google could also leverage its advertising infrastructure to increase revenues. Given how other commenters are highlighting the massive employee bloat at Twitter, especially in the advertising department, I can see this being the case here too (and am somewhat surprised at the report based on anonymous sources that Google are out of the bidding)."
