I am, and I've noticed one welcomed effect it has had in me.
I'll admit I had an unhealthy phone habit of mindlessly scrolling and Reddit nurtured this.
As much as I'm excited about Lemmy - the barriers I'm finding of finding content that appeases my desire to scroll has greatly reduced my phone usage. Smaller user base, inability (for me anyway) to find communities and content through the search etc.
Lemmy is just good enough for me not to go back to Reddit, but not matured enough to replace the addition.
