Getting the Tech Community to Adopt Encryption

Since most of the tech community disagrees with government surveillance, and tech community early adoption is often the catalyst for mainstream adoption, what do people think of getting the tech community to start using end-to-end encryption for basic internet services like email and instant messaging?

The first I've found is Silent Circle (https://silentcircle.com/web/home/), which provides end-to-end encryption for a variety of services. Does any have experience and knowledge of its reliability, or a suggestion for a better service?
