Reddit is unlike other platforms: Snoovatars. While old.reddit.com users can easily leave Reddit, people like me who use new.reddit.com enjoy seeing Snoovatars and how adorable they look. Many other sites have ugly profiles and bland formatting, but what makes Reddit great is the playfulness of the avatars because you feel like you are talking to your alien friends. I cannot live without seeing their faces :(
I never even used those because they let you use any image as a PFP before they even introduced those. I could have made my own Snoo and not had to use what they provided.
And I have that feature on Lemmy, too.
