It's essentially like encrypted Hotmail. From their site...
"Hushmail is a Web-based e-mail service that lets you send and receive email in total security. Hushmail messages, and their attachments, are encrypted using Open PGP standard algorithms. These algorithms, combined with Hushmail's unique key management system, offer users unrivalled levels of security. Hushmail's security is end-to-end; messages are encrypted before leaving the sender's computer and remain encrypted until after they arrive on the recipient's machine, where the contents are automatically decrypted.
Hushmail's encryption works automatically, transparently and seamlessly, requiring no specialized computer skills or knowledge.

Content Management Systems (CMSs) help create identity, community and collaboration, and Rich Site Summary (RSS) automates and fosters communication within and between these identities and communities. If CMS-based websites are like silos of knowledge on specialised issues, RSS is like the wind that blows between them, cross-polinating all the ideas, people and communities along the way. Aaaaaahh... sounds del.icio.us to me.
