I joined during the private beta and already gave up on it about a month ago. I ran into too many users that brought their Reddit toxicity with them. I couldn't take it. It looks like I only lasted a month; it seemed to start off OK, but went downhill quickly.
I see they launched the custom communities now, that didn't exist yet the last time I visited. Just scrolling through the front page, it looks like there is even less activity than when it was private, which seems concerning.
