And at the beginning everyone was worried about "Eternal September". It's only been two months.
People will come in waves, instances and communities will grow and die, just like how it was on reddit, we'll probably start seeing meme/politics free or even more specialized instances soon. But all of this is going to take time.
The turning point will be when companies/websites start spinning up their own Lemmy instances as their official one to replace their forums, which I think will happen.
So, being on Lemmy is a long term investment for me.
