Do you stumble?

I often stumble, both in real life and on the Internet. If you stumble on the internet, you use a web page or application. For me it is hard to decide what it is out of those two. Anyway, you register a profile and you can choose which topics you are interested in. When you "stumble", you are directed to a random page within the topics you have decided. It is possible to find quite som decent pages out there. Today, I found this one: http://www.amazing-planet.com. What you find there is stunning photographs from all over the world. I highly recommend it.
