Not sure when Lemmy first entered my social media walkabout, but it was quite some time ago now. I have been searching for a place to replace Reddit for years. It has been a slow search. That search has now speeded up since the latest changes. At present, I am using Kbin to gain access to the Fediverse. It feels the most user-friendly. Not that I have been here long, minutes. But I have lurked for some time.
I am not looking for a direct Reddit replacement. I think many are, so lack of users. Different rules, jargon, etc.... Do not bother me.
