The columns were out of alignment for me, so I thought I’d display it as a table:

> If I get it correctly, is like fakehistoryporn but for movies, right?

I think so, yeah. My own posts there vary widely in popularity (to phrase it euphemistically), so I’m maybe not the right person to ask though.

I wish you well. Personally, I’m a bit gloomy about the prospect of growing communities.

I was involved in an attempt to grow this community. Two or three of us posted on the 20th July and 21st July, and you can see the subs jump from 533 to 677.
I kept posting 1 post a day until the 27th, but found that, the more I posted what I thought was amusing the more you actually had to be me to agree. If anyone ever commented on a post they didn’t get or thought unfunny, there’s maybe something I could do about it.
From then, subs have grown (I assume the recent jumps are due to Sync users), but posts and comments have not.

So it’s not just about getting more subscribers - it has to be the right kind of subscribers.
Lemmy Kings sitting on porcelein thrones, dis-interestedly calling out for “More content! No! Not that kind! Get me some more Content Creators from the village!” are of no value.
If you’re increasing subscribers, but it’s still just you posting into the void, it’s hard not to get disillusioned.
