Poll: What is your home ecosystem?

Even though many, perhaps most people, choose an a la carte selection of sites for search, email, documents, photography, social network, etc. you probably have one that you consider your "home" in the cloud.

It could be a comprehensive provider of device software and cloud services, like Microsoft’s Bing/Azure/SkyDrive, Apple iCloud, or Google (or, even, Ubuntu One). It could be an Internet portal like Baidu, Yahoo, or AOL. It could be Facebook, or some other social network.

What is the center of gravity of your online life and work?
