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.
