Best concept ever!!

I love Stumble Upon!!! I used to use it years ago before there was an app for it... Rediscovered SU again recently and I have to say this is my favorite app/thing that there is ... I use it daily for hours, its very addicting. I have chosen physics, logic, music theory, chemistry, bizarre/oddities, etc for my interests and I find amazing articles. This is the best concept/idea for Internet surfing imaginable. I am so happy with this app.
