I've made a post just yesterday with some suggestions xD But I guess they were already working on a new one, and the generic globe was just a placeholder.

The new one seems to follow the same style as their Mastodon.world logo.

I think it's better than the placeholder, but a bit hard to read maybe.

And I particularly would prefer if the Lemmy instances tried to follow a similar design rules (in the logo and overall site design, and if possible in their names/domains lol), so it have a consistent branding and look more visually appealing to possible new users.
