Spreading joy around the world IRL: I sent fannish gift packages to due South fen in several countries around the world.
Spreading joy online: I gave no-strings-attached money (i.e., not for a purchase to benefit myself but for them to use however they wish) to Requiem Publications, that awesome long-time publisher of zines who continues to keep zine publishing alive. (Check out this link if you want to buy existing zines or have them create custom-order zines for you).
Spreading joy at work: I brought fancy snacks for my co-workers: gingerbread-flavored popcorn and figs with bleu cheese.
Spreading joy at home: I planned to have a More Joy Day Eve due South episodes-viewing with drinks and dinner at my home with pole_dancer and half_a_fanboy (but had to reschedule because of snowstorm).
