Re: Too much information
One team I was in charge of used to get pestered by the "can't be arsed" type of people you describe.
So I implemented an unofficial rule whereby the team would wait an hour before replying to any query which was obviously of that nature. During that hour, most of the people would realise that actually they did know how to do the thing themselves after all, leaving us to concentrate on the work which did genuinely need our help.
Thus our efficiency improved as a result. I would like to say it also educated the "can't be arsed" people, but it's more like it forced them into doing stuff they should have already been doing anyway.
