Because people here like history here's the historical run down:
In 2010 we did a cookie recipe exhange
Some years  it's just a whatever thread -kinda like this year
And the Holiday Greeting Card threads:
If your SBN-search skills are better than mine [and workman aren't pounding on the wall opposite your computer] perhaps you can fill in the missing years.
Since the fanpost section is sparsely populated these days sharing whatever holiday-ness you care to share in the comments is just fine and dandy.
Happy Holidays to all and to all a soft landing at the bottom of the stairwell.
