You're telling us we have unrealistic expectations when you've been here for 9 days. Clearly we don't have unrealistic expectations if we enjoy being here with its "limited activity" (compared to reddit). You just don't understand why we prefer it and are arguing instead of listening to people answer the question you asked.
I watched reddit grow for the 13 years I was active on it. I remember when it was small and just a forum like Something Awful and not the monster it became. I preferred that way. Lemmy is kinda similar to those early forums, but with its own idiosyncrasies. Be patient and wait to see if you like it, or fuckin leave, idc.
