I do now follow that account from my firefish.social account.

I joined it when the calckey.social server was less than a month old. I am definitely staying on board for the forseeable future.

Because of the social aspects it may be more like Instagram than like Imgur, but there is Pixelfed.

I have been using it for a bit since yesternight, so far I like it although I still kind of have to get used to it (I have been out of the habit of microblogging for like 6 or 7 years).

The UI is actually quite nice, with pretty good looking themes. There is a distinction between “global” (known network), “local” (your instance), and “social” (mostly people you follow), as well as “recommended” timelines. Features like channels I might explore some time in the future, so currently cannot say much about them.

Onboarding works quite nice with how you are being guided through filling in a profile, selecting a first few people to follow and writing a first post.

My Lemmy profile page shows my Calckey account, for those of you who wish to follow me. 😁

Well, if I were to remove my generalisation on age out of my comment, what would that make you think of it?

For the record, there are millennials who are now in their early forties.

I suspect (but never tried to test this) that the fedi in its current form mostly targets the ideologists (left and right), the tech savvy and (when generalising a bit on age) Gen X and younger. Ideally this would not be the case but right now it is what it is.

The Fediverse Observer has a stats page.
