I'm in the same boat. Not using reddit has resulted in time savings, but it comes also at a cost of losing a window into the world of people & their thoughts that I really valued. I have not yet found any place that acts as a front page of the internet, anywhere. I wonder if its even possible to get back to that in today's post-organic internet era, given the widely understood second order effects of using a platform as an instrument for dissemination of ideas/brands vs. organic content, and the suspicions that that awareness entails.
Even now, there are people running SMM account networks that simply take top or trending content on one platform, reformat it with AI, and post it in the same conversation on a separate platform-- effectively recreating the partial utility of a front page of the internet but only at the cost of inserting themselves as middle men who over time accrue gatekeeping power that is completely opaque from the outside. Not a new idea. Arguably an inevitable idea. It still sucks, though.
Lemmy is OK, definitely a smaller and more select crowd though. Tildes is also decent but fairly low volume.
I think there may no longer be such a place as “the front page of the internet” given the divergence in ideologies over the years and the overall decrease in civility. You have to pick a tribe. Even within the Lemmyverse different instances defederate with each other over differences in opinion and policy.
A new one will erupt eventually.
As someone who spends way too much time on reddit, before that I was someone who spent way too much time on twitter. And before that it was usenet.
Each time there may have been a rough patch when I didn't have a ready replacement, but eventually something grew to take its place in my heart.
