We post on forums to learn new ideas which textbooks and references can't give us. It's easy to learn from experience.

 

But I suspect I also get a little ego satisfaction, and I doubt that I'm the only "expert" here who experiences this. C'mon on, guys, admit it!

Well, there has been an instance or two when I've whipped up a quick schematic to post and said to my wife "dang, I actually am good at this stuff!"
