While I might agree with your sentiment, I think you're wrong here. How did he really 'help' anything? 'Use the search feature' isn't really helping, is it?
The guy may be sick of it, but if he was really sick of it he would simply post a link to the other thread to 'help' the other guy out. So, in a way he was being a A hole because he had to make his response and he didn't bother to offer any help.
And for the record search doesn't always work. I've searched things before and not have it pull up, only to start a thread and find out there was another thread days earlier that didn't pull up (for whatever reason) for me.
In short, if people are going to take the time to post an 'omfg, I'm so tired of u nubz starting new threads to ask questions already answered' they could take an additional five seconds to post the link to the thread they are referring to.
I know, what a novel idea, right?
