I don't know how many others here have ever used the Stumble Upon toolbar, but I highly recommend it. You basically personalize it to your particular interests, click the stumble button, and it drags up some random interweb page that appeals to your chosen interests. I discovered it my freshman year of college, and soon thereafter had nearly all the girls on my floor, and the boys above us following in my footsteps. ;D
Being the dork I am I have Psychology as one of my interests. As it's 5am, and I am not sleeping I decided to stumble. I found this wikipedia article pretty interesting, and I figured I would share.

If anyone else stumbles, would care to join me in stumbling, or just has a interesting interweb find I figured we could share them here. ;D
Happy Stumbling!
