My guess is a lot of people came in saw that Lemmy was kinda dead a lot of the time but suspected it would continue to grow so they left it temporarily to go back to reddit while they waited for Lemmy to catch up
Yeah i did something similar, though mostly bc i was confused about the whole instance thing.
Made three or four accounts over the first few days. I kept forgetting the password, or didn't really understand what an instance meant, or how to log on via Connect. Now that's done with, I just stick to one account
This is me. I bounced between a couple of instances before I settled on lemm.ee; I also am generally a lurker because I don't want to comment or post unless I know that it will generate quality conversation.
I'll personally post as long as it's relevant. Ideally it's an interesting comment but not always. I stay away from reddit-type inane comments with no substance, though I'm sure they have their place here as well.
