We don't have much family around so telling family is not an issue but we would tell them if they were closer. The closest family knows but they are overseas so it doesn't affect them or us in any way. As for friends, I volunteer DS3.2's Autism diagnosis freely. I noticed that those friends who know about it stopped looking at him with the "what is wrong with him? He's acting really weird!" question on their faces and instead, now they just enjoy him the way he is. So for me it has definitely made my life easier.
