you're right, the signals' products are usable, but they could definitely be better. i've yet to meet a website that couldn't be improved by watching customers and translating that feedback into an improved experience. totally discounting the value of watching customers to improve a product means that the discounter has never had the visceral "i suck" feeling of watching a customer stumble through a product he's designed and built.
