> Make a landing page easier for regular users to login, and prioritize login over signups...otherwise those regular users won't be happy.

This is one of the first "asshole design" moves that I recognize, that unfortunately most sites use. If the "Sign up" button (which will be used once by each user) is highlighted more than the "Sign in" button (which will be used hundreds of times), I know that your company doesn't really care about its users.

I'm surprised how common it is.
