Lemmy needs a useable search - either integrated or indexed via search engines. Major use of reddit for me is treating it as a giant forum, seeking answers to questions.
Doom scrolling comes second. I need a way to swipe away posts I have no interest in to hide them forever.
I will probably never be entirely done with reddit unless the knowledgebase portion dries up.
Im guessing that’ll be a long time coming. For most of the 14+ years I was on there the running joke was how horrible the search was. Idk if they ever really solved search internally, the difference was when results started showing up prominently in google search.
