I stumbled upon a blog recently that I absolutely loved. Check out the Pop Culture Dish! It is a must read for trivia buffs. Especially the Tuesday trivia. Test your knowledge of Pop Culture every week. The posts are awesome! They are filled with information that makes a trivia king's day! Its hard to find good trivia sites these days but this will keep you ruling the watercooler for quite sometime.
Another site I love is the site for the magazine Mental Floss. Incredible trivia on every subject. Often times we find trivia sites that dedicate themselves to only a few topics but this site is full of clever, witty and intelligent writing. Even though I am a University of North Carolina grad and this site is run by some Duke University grads...I have to give them props!! Ha Ha!!
AND if you want to see the craziest, smartest, most outlandish set of blog sites dedicated to all things yeateryear than go to Pop Art Diva's world!! That's all I can say...there aren't words to express the blog-glomerate she has created.
