Lot of people know who Snowden and Greenwald are now, I think fewer know who Laura Poitras is, sad to say I didn't before seeing this article.
For quick reference about these people see their Wikipedia links:
- Poitras http://en.wikipedia.org/wiki/Laura_Poitras
- Greenwald http://en.wikipedia.org/wiki/Glenn_Greenwald
- Snowden http://en.wikipedia.org/wiki/Edward_Snowden
Close reading of the NYT's article can provide some useful insights and tidbits to serious security.
I also want to note one comment by Snowden:
"I was surprised to realize that there were people in news organizations who didn’t recognize any unencrypted message sent over the Internet is being delivered to every intelligence service in the world. In the wake of this year’s disclosures, it should be clear that unencrypted journalist-source communication is unforgivably reckless. "
