I let people I work with, family and friends know that if I send out a broadcast email with everyone on a BC blind copy, then they really should not feel obligated to read the email. This allows me to send out general interest emails to a dozen or more people and feel like I am not wasting people's time. I don't use email lists, rather, I spend a minute deciding who might be interested.
This is cumbersome but it gets around problems of Facebook choosing which of your posts they will show your friends.
