Merriam-Webster's new dictionary words for 2008

Last year, the lexicographers at dictionary maker Merriam-Webster proclaimed w00t its Word of the Year. For 2008, they've added fanboy, webinar, netroots, and pretexting to the lexicon. Who cares? I do, because I find Merriam's online dictionary, more consistent, more focused, and better written than its wikified open dictionary or the Google results for define:pretexting. There'll be 100 or so new words in the Merriam-Webster's 2008 edition, due September 1. Meanwhile, I called the company and got the 25 most populist of the new entries as a teaser:
