Re: Ah, Traffic Analysis
"No evil secrets but encrypted regardless due to ssh."
In fairness, the article was specifically referring to PGP rather than any other encryption and (as noted by earlier comments) the decision to use PGP to protect a given email is a far more conscious one on the part of the "target" than (say) simply using SSH for remote connections. (Indeed, the latter is almost de rigeur even amongst n00bs for remote terminal sessions simply because there are no examples on the interwebs for running a telnet connection anymore.)
But I think I'm right in saying that if that email is sent to a foreign (**) email server via a STARTTLS-ed SMTP session, the spooks probably can't even tell whether it uses PGP or not because the metadata was encrypted in that case too. (**Foreign in this context means not in a country where the spooks can ask their friends to issue a warrant to the owner of the server.)
