Instead of Black Friday, let's have a #FediFriday and shop / support the fediverse community!
If you're looking for fediverse related merchandise, #FediMerch and the linked list of merch below are good places to start.
There are many developers, artists and other fedi friendly business people among the community to support as well. If you want to promote one today, just add the #FediFriday tag so people can find you recommendations.
