Merriam-Webster's new words

Merriam-Webster has announced that 100 new words will be added to the collegiate dictionary this year. Unfortunately they only list 20 on their website - I guess there has to be some incentive to buy a new dictionary! Of the twenty they list, I only know ten! Of those ten, only three are a regular part of my vocabulary - DVR, ginormous and sudoku. I'm not quite sure how I will work chaebol, crunk or viewshed into my daily life but it's still fun to learn to new words :)
