Media Temple.

Why Media Temple?

"Of the three leading companies that compete for the business of independent designers, developers, and publishers, Media Temple is the one that’s most deeply embedded in the design community.

They don't advertise and don't pay commissions for linking to their site, as another leading host does. It's marketing plan can be summarized in three words: host great sites.

...nobody supports the design and independent content communities like these guys. If they disappeared tomorrow, there would be practically nothing interesting to look at or read online."
