ohh, now it makes sense. I was referring rather to:

I try to move away from centralised aggregation like Reddit.

believing you subscribe to reddit or similar link aggregators to keep up to date with certain topics (subreddits, communities on lemmy), and usually by subscribing to the rss/atom feeds from which people share URLs most of the time and which you are interested on, then you mostly can discard such link aggregators. Lemmy offers rss feeds in case you want to follow up a community without subscribing to any lemmy instance, and I believe reddit hadn't killed it's similar rss feeds per subreddit.

However if it's just for one interesting post you find, then rss/atom feeds don't provide what you want. However, if you like a post from a rss/atom feed, most rss/atom readers allow you to include the link into favorites, so that they are available for you whenever wanting to come back to such post or to actually get deeper into it. Favorites would have a somehow similar functionality to pocket, but I agree it's not the same, since the sources have to come from a feed, as opposed to any generic URL, however if your URLs sources come from recurrent blogs or sites, and they offer rss/atom feeds, then this would work. I'm kind of following this approach to have my rss/atom personal link aggregator, :)
