Seems like there's a missing variable in this calculation: it estimates 7000 QPS for _posting_ tweets but doesn't include any information about _reading_ tweets. Those 150M DAU are presumably reading a lot more than two tweets per day...

OTOH, perhaps that omission makes this a more accurate representation of how Elmo makes decisions. :P
