I didn't downvote myself but I also see little advantage for a vegan group chat in comparison to the different public communities here on Lemmy. A pseudonymous group chat that's free to join for everyone doesn't provide much privacy and all the content would be unstructured. Thus, if interesting content is shared there, it will be hard to find it again later or share it with other people. I prefer a thread-based platform like Lemmy or traditional message boards.
