Courtesy and respect? Really?
In my point of view, posting questions and asking for help should include these points.
Asking sames question in different communities without letting each other know, forces people to waste their power and time. That's disrespectful in my point of view.
Although he apologized and seems to understand the problem, he didn't link to this post on SO.
And pretending that's all new .. doesn't make it any better.
