I began noticing on Reddit (official mobile app) that if I hadn’t viewed a community in a while, it would NEVER show up in my feed. I always assumed this was Reddit trying to play “Facebook” BS - safe to assume with Lemmy that won’t be the case?
I think the problem I’ve noticed with Lemmy is I tend to only get the more popular communities showing up over and over again. Reddit was at least a little better about showing smaller subreddits I visited in my main feed at least somewhat often. Not sure if I just need to change how I sort on Lemmy, I currently use hot and subscribed.
Try Top Daily to see new stuff. The ranking will be fixed in a future release of lemmy to sink old but successful post to the bottom of the page and sprinkle in small community content as well.
