Not explicitly answering ops q; what brought me here was a friend who introduced the Lemmy/fediverse. And this is (imo) a better alt to Reddit. It is filled with company accounts, spammers, banned or discontinued sub-reddits..
I'm sure you know this and have heard it, but for the newbies you have to change your order to get more content. Switch between hot, top 6 hours, top 12 hours, subscribed new and overall new. In that order for me. I rarely get to overall new because it's not addictive.
