How Often Do You Host Dinner Parties?

In case you haven't noticed, we're talking about entertaining and parties all month at The Kitchn. I love to throw a good dinner party, and I'm curious as to how much this enters into other cooks' habits and cooking. For the purposes of discussion, a dinner party is having others outside of your family over to eat — from casual last-minute pizza parties, to sit-down Christmas suppers for 12. How often do you host and cook for others?

Personally, I tend to have people over at least once a week, and to take food to a potluck every week or two as well. Does this sound like a lot? Not enough? How often do you entertain, and if you don't very often, what holds you back?
