I'm going through the same thing with Lemmy. Can be confusing knowing what instance you're in especially if scrolling through it by the "all" filter. I'm enjoying the experience of something new, but it misses the magic of Reddit in the past, as the niche subs just aren't there yet. I'm still finding that daily need to go on Reddit to check my favourite subs as there is nothing to replace them yet.
Lemmy is definitely showing promise but it's early days!
There's "fuck spez" content in the middle around the 3rd party apps sign, but nothing like it was a day ago.
