This is 100% on the user. You have to follow folks and hashtags and actually interact to really get the most out of it. No one will serve content to you.
Which mobile client do you use to “follow hashtags” ? Otherwise, I’m doing all of the above, but there’s just too little diverse content compared to twitter. Also, it’s actually funny to get told to “actually interact” on a post when I’ve literally interacted to provide feedback when nvk asked about what issues we had. 🤣
