Cohost is really starting to feel to me like a site where even if only a couple of people interact with a post, there's a good chance that those couple of people really did appreciate seeing that post and they're not just scrolling through clicking like on things.
So post stuff. And tag it so people looking for that stuff can find it. Don't worry about who or how many people are into it. Because there may just be those one or two people whose day is just a bit brighter because you shared a thing.
