Yes, it's 13 hours into the NaNoWriMo and I have written 1, 915 words. Which means that I am already 249 words ahead of the daily word count of 1,666 words. The word count widgets aren't available yet, but when they are, I'll add it to the blog.
Edited to add: As of 10:49 PM, I have a Day One word count of 2053.
Also, I'm a NaNo Rebel because I'm working on a previous work. The great thing about NaNoWriMo is that even though the rules say that coming up with something from scratch is best, it's not a hard and fast rule. In fact, to quote Captain Jack Sparrow, "they be more like guidelines."
There is even a forum for the Rebels--people working on previous work or revising previous NaNo novels or working on non-fiction or academic pieces. You could, conceivably, write your thesis by NaNoWriMo.
