What kind of things would people be interested to see from this account?

I wanna post stuff on here, but I don't really have the habit of blogging about my life. I was thinking on taking about my series idea, or dump all of my creepypasta headcanons and other shit like that on here, but idk if people would engage with that lol. 

Not looking for popularity or something, but just a community with the same interest, if that makes sense. Tumblr's a good place, but there's not a lot of conversations and it's more about circulating info rather than having a discussion about it lol.
