Re: Respect to experts I agree. I'm a licensed P.E. and I ALWAYS ask for help from the trade masters (not so much from the helpers) when non-typical situations come up. I figure they're more likely than I have to have seen it before and I'm always willing to learn.
Sometimes I just know when to leave stuff to the pros. I had a new garage door installed at my house a few months ago. Yeah, I'm an engineer and yeah, I know how those doors work, but I asked the installer if he wanted any bottled water or if he needed to use the bathroom -- otherwise I left him alone and told him he could knock on the door if he wanted to talk to me.
He was really surprised later when I told him I was an engineer. He said that he would've expected all sorts of supervision, free advice and "guidance" during the job. I told him that I figured he could handle his own job.
I come here to learn and learn I have. The real professionals here are awesome for taking the time to share their knowledge with the rest of us. A very big THANK YOU! from my heart to all of you!
