Cheers where it works, but some projects aren't sexy enough to attract a self-sustaining community, and when you don't preselect success stories but choose according to external needs that hit-and-miss experience starts to look less obvious and more like the thing only "smart" people can succeed at.

My objection is to the idea that FOSS is easy... it does require some smarts to succeed with.
