Interesting concept, and is apparently being promoted by a guy who's local to me:

The World's Biggest Party For Writers
November 15, 2004 will mark the third anniversary of I Love To Write Day, a grassroots effort to have people of all ages practice their writing skills. Created by Delaware author John Riddle, I Love To Write Day is an opportunity for people of all ages to write something: a poem, an essay, a letter to the editor, a short story, start a novel, finish a novel…the possibilities are endless! On the first I Love To Write Day, 11,328 schools all across the country held special writing events and activities. Last year, we signed up 12,007 schools. This year our goal is to have an I Love To Write Day program in over 15,000 schools. Please help us spread the word: tell schools, libraries and bookstores in your community about I Love To Write Day.
