Lemmy equivalents to subreddits

Hello new friends! Of course I'm a new member having abandoned the shit show that has become reddit and am starting to get the idea of different instances and building a new feed for myself. I saw a post that had some Lemmy equivalents of popular subreddits such as /r/pics and /aww and what not but I've since lost it. I saved the post for later and this morning my saved post was for a comment in an unrelated post. I'll figure out what I did wrong eventually but could anyone help me find this post again? I've been searching all morning and having no luck figuring out where I was when I saw it or how to get back
