@b0rk so good ideas!
One kind of person who helps me a lot is someone I can ping with any weird behavior I can't figure out, or any design problem, and they will take a few minutes during their day to look at it with me.
They won't have the answer right away, but we complement each other very well, they ask good questions, point flaws and suggest ideas that'll make the solution appear in no time, sometimes just by explaining the problem to them.
