Happy Holidays - NYTimes.com Merry Christmas, joyous Kwanzaa and happy New Year. We hope you're surrounded by friends and family, eating festive foods, giving, receiving, and generally enjoying the holiday spirit via traditions old and new. Through Jan. 1, we'll be on vacation ourselves. We'll look in on the blog now and then, but if you post a comment, you may not see it published for several days. Don't worry: As always, comments will be saved in the system until we read them, and we'll post them all by Jan. 2. So if you're taking part in our 2013 "Year in Rap" contest (and we hope you are!), please feel free to send in your submission over the holidays. What else can you do while we're gone?
