pandora.com is the only webapp (apart from google and reddit) that has profoundly affected how I spend my free time. I feel a rush of adrenaline every time I discover a new artist in my areas of interest (some rather obscure ones: salsamuffin, anyone?) The concept is so brilliant and offers so much potential, it's scary. Especially when pandora.com starts using AI pattern recognition/clustering instead of their 'human experts'.
