I’m loving it too- I miss a lot of subreddits and the sheer volume of content from the other site, but it feels quite special here at the moment. Also I am loving how quickly Lemmy and all of the supporting apps are developing! I am using Mlem and am very impressed. I want to like wefwef and agree that it is very similar to Apollo, but I just can’t cope with web apps.
I first saw these advertised when I was at primary school in the late 80s early 90s I think- the branded ones were called “Scatch” i believe.
