I don’t know how accurate the stats are, but around the bottom of each instance sidebar they have a breakdown of users per day/week/month. I think that’s supposed to pull not from signed in visits but whether they were active by voting/commenting/posting.

Excluding the instances you mention, there’s still a sizable amount of people active if those stats are reliable.

You can see the weekly/monthly stats aggregated in the list view of instances on Lemmyverse:

Image uploads are enabled 4 weeks after account creation, & image upload limit is 500kb per image.

Source is instance sidebar, but if you’re using an app that’s gonna be found in a variety of places. In Voyager for example it’s under Communities>3 dot menu in the upper right>Instance sidebar.

Also while there’s a modest amount of people here (I’d reserve small for under a thousand online, personally), many of them seem to have a rather narrow set of interests they like to engage with. Namely technology (self-hosting & Linux in particular), news (primarily to do with politics), and memes (a mix of things but largely politically-tinged, old memes, nostalgia-tinged).

Outside of these interests the next most active may be cute animals, comics, and video games with some gradually rising gardening, stitching, woodworking, art, and certainly other interest communities I’m forgetting or haven’t noticed.

It’s great! Also for anyone that happens to be in the overlap of people that enjoy chess and go, and want to play go online as well, there’s online-go.com.

I don’t know that it has all the features that Lichess does, but it does have puzzles, tournaments, custom games, and so on.

Gonna take this as a jumping off point to mention some software.

Wanna get into video editing? Shotcut’s pretty solid in my experience.
Into mind-mapping stuff? You might give Freeplane a look.
Have a drawing tablet & want to use it to take handwritten digital notes? Check out Xournal++.
Cross-platform Notepad++ alternative? Might give CudaText a try.

Could list off more but will leave it at a few for now.

In terms of fully free, obligatory mention:
Your library may offer more than books alone, depending on how well supported they are. Borrow music, movies, sometimes even video games. For music and movies they may also offer these to borrow digitally as well via online services they coordinate with.

I don’t think so. The largest ask communities, according to their own descriptions, say they’re for more open-ended questions, albeit [email protected] seems to be more lax about it (and it seems like maybe [email protected] has kinda relaxed on it too).

There’s the newer [email protected] that doesn’t have the open-ended part to their description, so might be a good fit.

Ubisoft cannot complain when gamers “pirate” their games then.

If buying isn’t owning, piracy isn’t theft and all that.
