This fresh influx of Reddit users into Lemmy is definitely a strong opportunity for Lemmy to expand and it needs to capitalize on it. The next big hurdle though is going to be porn. Currently nobody allows porn on Lemmy because it’s too much of an administration headache. If they were smart (and they usually are) an enterprising porn network like PornHub should stand up a Lemmy instance to host porn out of. If Lemmy doesn’t come up with a solution for porn though I’m not sure it will actually be able to truly replace Reddit.
