Much blaming the victim going on in this thread. Why don't we be nice, and just answer questions instead of being bullies.
Who exactly do you see as the victim ? The one who refuses to spend a few seconds googling the answer to his question or the ones trying to teach a man to fish instead of simply feeding him and receiving grief for doing so ?
Yes, it usually is very helpful, depends on who is answering. Some really wise guys, sent you four answers, as you can see, when they could have simply answered your question in the same time. Sometimes people need to feel supperior to others, it is only human. Forgive him. But I agree it is sad....
