Public vs. Private Spaces:

You should be aware of the boundary between public spaces and private spaces. When you share new information, you have a wide variety of choices in both communication medium and audience. If you are not able to define which will be the right medium and who will be the right audience for your shared information, it may not be effective as you think. If your message does not intend for a large group of people, then don’t post in public. If your message is only for a few people send it as a private mail.
