I would have assumed spacey topics would sell like hot buns.
I guess Physics are more of a niche and you would probably find more armchair physicists here than actual physicists.

Agree.

Even simple things like subs for particular cars/car brands were thriving on Reddit but don’t exist here.

If things need more activity try posting, it works great

I wish there was a better way to port communities over here. There are people complaining that Lemmy shouldn’t copy Reddit (I say, why not?), but then there’s legitimate complaints about homesteaders running to Lemmy and snatching up all the popular subreddit names.

except no one comment and no one posts
