I find Media Temple to be a perfect fit for a mostly-front-end person like me. I'm not an idiot, I'm pretty experienced with web work, but I don't really wanna be in charge of setting up and configuring a server. That's a specialized set of knowledge that I think is well suited to the people that own, sell, and support servers. (I think that would be a pretty good career choice, FWIW, kids.) That's what Media Temple does in spades. They own, sell, and support the heck out of servers.
That's true at all levels. They have super affordable WordPress-tuned servers and shared servers that cost less than a dollar a day that can host more sites than you'll ever need (500!). You can scale up from there with virtual servers (that's what I have) and up to dedicated servers and even fully managed AWS stuff, if that's the kind of power you need.
