1) It seems that the NSA is intent on cataloging every connection of everyone in the world. The best way for "secure" communications then would be to send encrypted messages to a few thousand random addresses, only one of which is the intended recipient with the private key necessary to decrypt it. Everyone else can write it off as spam.
2) I thought it funny that NSA took the time to write in the slides that they are annoyed by Android's IMAP implementation ("Android implementation in particular uses a lot of bandwidth").
3) Why release redacted versions of stolen documents whose release in any form is a violation of federal law anyway? This is like cleaning up your mess after robbing a bank. Might as well release the whole thing.
