I curate/mod !tycoon@lemmy.world. It’s dedicated to “tycoon simulation” and management games. Things like Rollercoaster Tycoon, Transport Fever and Project Highrise.
While engagement and posts not made by me could be better, I feel like there is a solid growth trajectory.
I also have a Mastodon account:
https://mstdn.games/@Landgraab_Industries
I cross-post (manually) more prominent posts from the Lemmy community. I do get some engagement, but subscriber growth is very anemic.
I always add tags and I try to make the posts appealing.
Any other tips to help gain (organic) subscriber growth on Mastodon?
