I quite like these - in fact, my girlfriend glimpsed at my computer today and saw me browsing Lemmy.world. I explained what it was and her only conclusion was “cool. they could use a better icon though”

I’ve been adding icons with the mascot to my communities too - I think this touch of “branding” helps a lot with newcomers joining in, because they get confused with the multiple instances and servers, so if you make everything look a bit more uniform and connected through the icons it helps.
