Just like Manish, I too do not agree with what Andrew is saying. It is ridiculous to compare DropBox, Linkedin, Quora, pinterest to the home page of some unknown startup. I am also not convinced you can do any kind of testing for homepages for startups which have very low volume traffic.

IMO, I think you should just stick to your gut feeling, do what looks and feels right for home page, if this mean putting more content, so be it.
