As good as I feel Lemmy is, I find a lot of the meme & humor communities alarmingly depressing.

I'm not looking for 24/7 wholesome! But, man.. I just want to see funny memes.

I'm trying to do my part by posting more content.

It's decent after blocking all the fluff/low-quality communities. But it needs a way to follow threads & highlight new comments.

Slowly and steadily, yes.

i find it's mostly content my older colleges in tech would find funny

Yes, it is so much better, sometimes I forget Sync for Lemmy ain't Sync for Reddit.

Honestly, kind of but maybe not really. I mean, yes there are improvements of course, but a bunch of them aren't very visible, and of course I understand that. It just feels very stable.

It kind of just works, for the most part, which is a good thing - minus this bug which has been fixed over a month ago but I guess is not live yet on every instance: https://github.com/LemmyNet/lemmy-ui/issues/1968 because I still run into this bug, and it's still annoying unfortunately.

Outside of that, there's not really too much going wrong for me to notice any huge improvements.

edit: Oh, it's because 0.19.0 UI has not had a stable release yet (nor has 0.19.0 server), once that releases as long as there aren't many regressions I won't really have any more complaints about Lemmy (other than maybe the non-SEO-friendly URLs).
