When you redesign a new site, how do you know users are going to like it? How can you ensure that you know how the redesign will sit with existing as well as new users?

The idea that you can educate users about how to use a user interface is misguided. The goal of usability is to create intuitive user interfaces. Intuitive means the design does not require understanding. Help and "user education" presupposes that both of these goals are possible.
My personal and professional experience tells me they are not. Maybe I am not typical: I don't read user manuals, I struggle with help systems and I go for defaults over configuring options. In fact those three behaviors are very typical of the "average user".
