If you create a community, please try and populate it with content. I see a lot of new communities with 0-1 posts from the mod. That’s not nearly enough to get people engaged - users are going to see that it’s a ghost town and leave.
If you have enough interest to create a community, you probably know something about the subject matter, so PLEASE add some posts (5-10 would be a good start). Maybe some questions to get people talking, even popular reposts from other sites. It sucks shouting into a void, but if you don’t do it, everyone else will also be shouting into a void.
Also please consider whether you need to create a community! When there are 100 million users of the site, there may be 1000 people who are interested in the same exact niche tabletop RPG as you, but there are <500,000 users here for now, so you’ll be lucky to find 10. Consider creating a thread in a broader community (like boardgames) until you have enough people talking in the thread that it gets messy - then it’s time to create a separate community.
Thanks for coming to my TED talk.
Tip for those creating new communities: don’t slam your fresh community with loads of new posts all at once. Pace yourselves. Create 2 or 3 new posts initially. Then over the next day pop a new post every few hours.
The net result is the same (content!), but you greatly reduce the risk of people blocking your community. I look a lot in local, sorting by new. And when my feed is deluged by posts for the same brand new community, I tend to block that community because it’s smells like spam. And I’m probably not alone in doing this.
