For what it's worth I still think the name is great. The meaning of words change. The identity of Hacker School is strong, and I could easily see it deciding what hacker and school means in the future, not unlike YC and the words hacker and incubator. Granted, it's an uphill battle, but the name recognition is strong, unlike Foo Bootcamp (I might be biased in this regard, but friends have remembered the name without being prompting just because it sounds cool).
