Stackoverflow is like a big stage before thousands of spectators and you're a newbie at this tossing yourself into it. You rehearse fiercely before entering the stage yet some fashion queen will nitpick on your outfit and others better than you will boo ruthlessly at your performance. But a selected few, the little jewels in the sands, will come to you in your confusion and say "hey... I know what you need to better. And I'll be glad to share my skills and wisdom".
