Ask HN: What technologies can we use to minimise data collected into PRISM

We all now know the news about PRISM, so I was wondering on your thoughts on how we can stop the majority of our data going into PRISM. So I thought this would be a good Forum to discuss the technical approaches to minimizing our Data making it into PRISM? There are essential services and tasks that we all use and do and I was wondering what suggests we as a community can provide to minimize the Privacy Invasion.<p>Here are some examples: Browsing: Tor Email: Private Mail Server with PGP Social Network / Media Sharing : Diaspora? Storage: Mega? Etc.... Looking forward your comments.
