Stumbling in the Dark

So, I registered for StumbleUpon and it looks like a pretty cool place to hang out if one were interested in getting lost in this labyrinth of interests. I did "stumble" on one interesting place but doubt that I'll use it beyond this exercise. It's good to hear about these things so I know what people are referring to in conversations. However, I haven't heard anyone talk about StumbleUpon yet - so I'm one stumble ahead of many I think! Yay!
