+The importance of data availability
+===================================
+
+Users today demand high data availability in their applications. As a user
+switches from device to device, the expectation is that each application will
+reflect the same state information across devices. Additionally, if all devices
+are lost or destroyed, the contemporary user expects to be able to restore her
+or his application data from the cloud.
+
+In many ways, data availability has become a necessary precondition for an
+application to be considered "user friendly". Unfortunately, most applications
+attempt to provide high data availability by rolling their own custom solution
+or relying on a third party API, such as Dropbox. This approach is has several
+drawbacks: the user has no control or access to the data should they wish to
+switch applications or data providers; custom data synchronizations schemes are
+often an afterthought, poorly designed, and vulnerable to attack and data
+breaches; and the user must place total trust in the provider to safeguard her
+or his information against requests by repressive governments.
+
+Soledad provides secure data availability in a way that is easy for application
+developers to incorporate into their code.
