Agreed, the top suggestion here is a community I've been subscribed to from day 1 and it's always felt dead. Lemmy is good for specific tech niches but outside of that it feels like the same generic meme stream that /r/all is. Also a red flag that nearly all of the communities listed here are attempts to recreate a reddit niche 1:1 which obviously was never going to work as long as the main reddit version is still around
Unfortunately I don't think recommending dead communities with 9 MAUs and 1 post/month is the solution to building up Lemmy's userbase but I respect the attempt
Even their "correct" functionality is sketchy AF, the average user would still have no idea what that URL tag meant and thus would not be making the informed choice the article implies they would be making
