The thing to keep in mind if you are on a Fediverse instance right now is that you are a very early adopter.

We're still in the stage where we need people acting like bees. Go out to the greater web and find web sites (REAL WEBSITES, NOT AGGREGATORS), and bring back their content. Stuff that has some actual meaning and teeth that can enable people to make comments.

If you're a commenter, you need to get in there and engage with people. Not every comment needs to be a top level comment. If you see someone has said something, and you've got a response to it, even just a conversational one. Post it.

And finally, memes and images are cheap content. They can be looked at and consumed quickly which makes them great for lurkers, but awful for community building. You need actual content for that.

This is the hive, everyone here are drones, if you want the site to thrive, you need to bring back high quality feed material and you need to communicate with your fellow drones, not just hope that other people will communicate with you.
