This thread is excellent, love all the replies. For me:
1) Perfection is a myth (and I hope nobody invents the
perfect razor, otherwise sites like this wouldn't need to exist

)
2) Choice and variety are a luxury, I feel very lucky to have found something that aims to provide choice rather than restricts it. Not many product categories can say that is their aim, they want to lock you into an eco-system
3) A shared common interest with others that isn't based on competition/showing off but about sharing and informing.
