Half the success of Lemmy is not becoming the three ring circus of Reddit.
How long will it last? Idk. I've already seen people complaining about AI bots blowing up their instances with requests, mining for data. I've already heard complaints of bots manipulating votes on certain subs and accounts.
If that gets worse, Lemmy gets worse.
But for the time being, we're mostly just a large community of terminally online nerds doing our things and sharing amongst one another, which is what Reddit was supposed to be about.
