I feel like it's both niche and not niche enough. Reddit has subreddits for all sorts of book series I enjoy but fediverse, if it has them at all, is largely empty of activity competitively.

I really want them to come out with an MMO mouse now. I like having numbers on the side...

I'll believe it when I see it, but maybe this is why my 4 year old laptop is near unusable on windows 11 :(

Pretty sure absorb is foss, just not available on the fdroid store.

Yea Linux is the plan. I moved my desktop to Linux a while ago and stopped using the laptop. It's only used occasionally while traveling and I just haven't done the move yet.
