I think there is a lot of hype going on here about migrations tbh. Lemmy is cool and all but reddit is certainly still generating/aggregating way more content and its where most lemmy content is originating at this moment. I think for now the tech folks are here setting up, a few of us are bumbling around discovering this, and everyone else is still on reddit. I am not a very techy person myself and lemmy is a weird system to wrap your mind around coming from reddit and I can see how people may not bother, especially this early. Just choosing an instance and then finding communities is like an absolute mindmelter if you're used to reddit and its' easy to see why people on reddit would not be keen to move away.
