I read a lot more using Lemmy than I did on Reddit. This is mainly because I have a rule, if I post it, I read it, then there's all the interesting blogs people post to read.
So, find a community, maybe you're country/state maybe a field of study like philosophy or geology. Start finding relevent and active publications visit them regularly or setup an RSS reader, post then comment often on the texts you find. Even if its just you posting in the community, you'll find people tend to breeze in when something interesting happens.
But don't just read, comment and try to consider the article, blog or essay rather than just consuming it. I listened to a podcast with Cory Doctorow a couple days ago, he said blogging has been a fantastic way for him to develop ideas, then revisit them and develop those ideas even more.
