To the responses so far, I would say:

- it is true writing is a security compromise in any form (never leave a paper trail!), but there is a difference between a letter locked in someone's filing cabinet and an email stored on a server that theoretically anyone on the internet could hack into
- I'm not talking about payment information or SSNs. Your name is attached to your email, so suppose you share your thoughts about whatever thing you don't want the world to know, it comes to the attention of someone not your therapist, and then becomes public in your circle?

It's not the same as a compromising photo on Facebook getting your career derailed or Ashley Madison getting hacked, but there is a danger - I'm just curious how people deal with it (or not).

I am not saying what people should or should not do. I have already made that decision for myself, and no one else's decision troubles me at all. I am only wondering how founded or unfounded others find my concerns.
