I tend to be like that, but on the other hand I'm easily pissed off when someone will ask a question I already answered, like coming to a meeting and asking what the topic is or where they can find the documentation I provided in the invitation... Basically I put a lot of efforts in sharing information and people say they didn't had it only because they didn't care about, I have a hard time accepting it. Moreover because it's always the same persons. So, while I'm working on not overreacting in those kind of situations, I'm also accepting the fact that I can't make people care if they don't want to. The one who cares are thankful for the information. Those who don't, well, they don't.

No, this is perfect, as a manager you can hardly "over-communicate". I wish all managers would do that and also reflect about their communication to constantly improve it.
