Useless Knowledge..

While I was browsing for a widget to be added on my blog page, I saw this interesting (for me) widget, I tried it to find out what could it be, then TADA! it's a random knowledge that generates every time my blog page is being reloaded (PERFECT!)

I'm not sure if they do really share a precise knowledge but we can always find it out, right? well, only if you're having doubt about it... DUH!

The widget islocated on the left pane (3rd column from right) next to my chat box.
