Trying to be active in communities and filtering out communities and domains I don't want. That way it's sort of a reverse curated list. Not communities I selected to view, but everything except the ones I don't want to view.
When you post something, the post is on lemmy.world.
For example, this is your post https://lemmy.world/post/7469149 . If you would post to another community, it would still be lemmy.world/post/xxx even if the community isn't on lemmy.world.
But the post is attached to that community.
All is all the post from all the communities the accounts in your instance are subscribed to.
"Subscribed - Hot" is my normal and then once or twice a day I "All - Top 12 Hours" (or Top Day if I haven't checked in a while).
I've got enough subscribed communities that Hot separates most of the chaff and still has a handful of new threads every hour. Then All - Top 12 hours show's me the day's best memes.
I start at top of day, then 12 hrs, then 6 hrs, then 1 hr and then new. All, not subscribed, of course. It helps that I'm on a small instance where basically everything is interesting and it's not flooded with posts.
I get caught up on Subscribed - New and make sure I've seen everything, and then if I'm still bored I'll go to All - Top Day or 12 hour, and then if I've seen most of those I go down to Top 6 hour
Next to the dropdown with sorting options, there are two icons: one is "sorting help", the other is RSS. Copy that link into an RSS reader and you need never look at the feed again. All the "Top" (or whatever) items will get mixed up into a feed of whatever else you're reading by RSS.
It depends on when I looked last time. Mostly Hot is new enough so I didn't see it before but also interesting and no spam. If I look very often then New. If I didn't look for a couple of days then Active.
Hot/All - I have it set to show NSFW, but I block most of the NSFW subs individually or the people who are just trying to push people to OF. Problem is on old.lemmy, you have to visit the group you want to block if you want to block it. So my history looks like a lot of me going to yiff/gay/rape/incest/torture shit...but there's no button to block it on the mlmym version of lemmy unless I go do the stupid group directly. Author says he implemented this functionality, but it doesn't work in FF.
