Up until 3rd party app devs announced they're converting their apps to Lemmy? Yes.
Now, absolutely the fuck not. Reddit is a cesspool compared to when I first joined in 2013. Lemmy feels a lot more like reddit did then. It's quaint and cozy here. Yes I'd like to see this place grow some more. But 1/10th the size of reddit would be plenty. Most reddit users don't contribute anything useful anyways so no loss there.
