Myth #25: Aesthetics are not important if you have good usability
Aesthetics is no substitute for usability for sure, and if I had to chose, I would pick usability over aesthetics any day. Except when pithing to a VC or a marketing person, then aesthetics always beat usability. But I think the two concepts are fused at the hip – if you care about the user experience, then you do both.
The problem is that you may know what you like, but you are unable to create it, so once you find a good graphic designer hold on to him/her.
