I'd love to hear some thoughts about customized Homepage vs customized Dashboard, as a starting point for different user types. Meaning homepage content is customized for new and returning visitors, while dashboard becomes a homepage for anybody who already has an account (registered, subscribed and expired users). Many examples of this, Facebook, Twitter, Couchsurfing... Still, some sites decide to use their homepage as a starting point for both logged in users and new visitors, Amazon and Airbnb, to name a few.
To me the the first is a much better option, it's easier to customize (especially layout wise). Also, users who already have an account need their own tools and personal content to be as close as possible.
Am I missing something here? Does anybody see any other reasons why one would choose to have a homepage as a starting point for everybody?
