The idea that you have all these experts waiting in the wings to do stuff is an illusion in my experience. There's really just a bunch of amateurs muddling along trying to do things together. The people that are truly experts are too busy to even help, right?
And if the experts are too busy to help, what difference does it really make if there are experts at all. Because the whole point of this endeavor is helping other developers, and whether you're an expert or not, if you have no time to help, you're not really contributing to the solution.
