The biggest, most significant reveal at this stage of development is that Pixelfed’s groups feature will be launching with compatibility for both Lemmy and Kbin, officially connecting Pixelfed to the rest of the “threadiverse” that the other two platforms occupy.
From my understanding, we’ll be able to see Pixelfed groups on Lemmy just like any other community and follow them. There could be a group/community, where people publish photos of cats, their art, urban photography, etc.
