I guess personal finance was a bad example; in the hour since I made my comment two people have replied about that but no one has really mentioned hobby style communities (the others i mentioned) which leads into the second main issue I see which is that Lemmy’s userbase is not a casual one.
Almost everyone one here can tell you what an API means, where as the vast majority of people who are doing Google searches with Reddit at the end probably can’t/don’t care about it. That’s leads to an over representation of the ‘smart communities’ like Linux, Technology and Personal Finance. Since there are many people migrating to Lemmy that are already interested in those topics, the expertise is a lot higher.
Meanwhile, I don’t think a lot of people who would frequent Reddit for cooking advice, home improvement questions mechanical questions and other topics like those made the switch so easily. And no matter how many times you post in this subs, it’s not going to bring people from Reddit who didn’t want to leave in the first place.
Plus, when it comes to people asking questions related to things they need to do in real life, they need an answer. I made a bunch of posts on some communities here about an issue in a new rental house and got no comments on it at all. I’m all for trying to get Lemmy bigger but I can’t do that at the expense of the things I need to do in my day to day life.
I’m good friends with the lead singer of a band who has 225 monthly listeners on Spotify, which is pretty good considering they are in Cambodia.
