Yeah, Lemmy still has nowhere the size of Reddit. I personally prefer it here, but I imagine managing a small community can be rather lonely.
That said, I love to lurk in the smaller communities, and I love to see your posts.
Only "FOSS this, Linux that" and sometimes war-related news can get a little tiring, and while photography and SuberbOwl seem to do fine and ImaginaryX still is around, it doesn't feel like much is else going on.
Don't let yourself feel chained to this place and get depressed, that's the last thing we (I) would want. If you feel that the engagement level here doesn't meet your needs (especially seeing that you are virtually the only one keeping this community alive), then it's totally understandable to seek a community that better accommodates you. You could always be both places in the hopes that Lemmy might pick up speed someday, but I wouldn't blame you if you chose one over the other.
TL:DR: We love you, but not enough for you to sacrifice your health or mental wellbeing. Stay safe, stay healthy! (I hope that didn't come off wrong.)
