Is Pinterest really that much different in scope, or at least less "pie in the sky", than Twitter, which regularly makes the HN front page for not just tech/design posts, but even for being down?

But I'd expect to see more HN submission/discussion from its engineering blog [0], given Pinterest's success at scale.
