We use usertesting.com for various projects. It’s a great service to get verbal feedback and recordings of users talking about your web site & landing pages. We use it quite a bit for our game developments to find bugs in browsers we don’t have as well as get feedback on playability and the ever elusive “fun”.
Often times when we ask friends they answer “in kind” meaning they tell you it’s great because they don’t to hurt your feelings. This will give you much more honest feedback.
