Same, am I the only person that uses inner/right joins? A lot of times I'm not doing it in order to minimize subsequent calls, but rather because the logic of my query depends on being able to do a join. Obviously my understanding is that at Facebook-scale you're not really able to have the luxury of joins, and have to accomplish your query logic in other ways...but that strikes me as joins being something you have to relinquish if necessary, rather than being a premature optimization.
