I would argue that Mediatemple kind of killed themselves in many ways, I can't see how GoDaddy will do much worse to be honest. People put them up on such a high pedestal as they got bigger, they just couldn't live up to their glowing reputation because of how big they were growing which is a problem not many companies can say they have, Support stayed timely until the end, but Media Temple lost out to Digital Ocean and Linode big time and just couldn't keep up in the end.
I wish GoDaddy all the best, but for the moment I am very happy with my Linode 1024 virtual server plan which never buckles under anything I've thrown at it thus far. Even hitting the front-page of HN once upon a time didn't cause it to break a sweat.
