You're right. SO is optimized for people who read it later. I.e. people who will Google their problem, get directed to the question...and then want to throttle you for answering "Just google it." Because they just did that. And the next eight links on their google search also link to forums with people saying "RTFM", "Quit wasting our time", "This has been answered a bunch of times before.", or even worse, someone who clearly didn't bother to read the question and gives a blatantly wrong answer. And then the answer they have been looking for is now buried in legions of programmers' impulsive expressions of indignation. At the very least link to somewhere where it is properly answered, or don't answer at all.
