I believe people just are not used to lemmy and therefore have trouble navigating. For example /c/technology@beehaw.org is being displayed everywhere as “Communities you might want to subscribe to”, so there are a ton of users. But thinking of something you want to subscribe to, and then searching for it, and the deciding which community to choose if there are multiple are a lot of steps. So it just takes time for people to come o think. If I think back in the beginning I also joined just a couple of subreddits now I am subscribed to over 300.

It takes time (that is if people don’t loose interest in lemmy…)
