Inviting friends over for dinner is the ONLY way I can get my wife and daughter to clear their stuff from the common areas.

A party with 10 guests is even better.

All three of us are hoarders, to an extent, but I alone am able to go into a cleaning frenzy approximately once or twice a year and get rid of mega-junk. Unfortunately, they don't seem able to do so.

So, I consider dinners still to be a useful tradition, though perhaps the motivations have shifted a bit.
