That part specifically refers to things built on the Stack Overflow API. And "generally okay" is of course hardly a guarantee. "Overflow" as a word is fine, obviously, but it does sit in the same "get answers" space – I can name my restaurant "Best Apple", but I'll have more problems if I named some piece of electronics "Best Apple".

It's your site, you can do what you want with it and you're free to ignore my comment – that's fine! But personally, I wouldn't have named it Answer Overflow.
