Anyone participating in NaNoWriMo this year?

For the past two days, I've been writing until my fingers turned numb just to say that I'm participating in this years National Novel Writing Month. So far, my word count is just shy of 4 thousand. I suppose I'm doing ok but yet to me it doesn't seem like much; maybe because I'm just starting. Anyone else taking part this year? What are your thoughts? What are you writing about? Curious minds want to know!
