Stack-overflow is amazingly effective, especially when one considers the alternatives like those countless forgettable websites heavily laden with front-and-center ads, and the ones that have nag screens that block responses to answers until you "sign up", and the ones with clueless dilettantes fumbling in the dark. My only concern is that I think the exchange community might get fractured/diluted if there are too many separate stack exchange sites.
