It sounds like you’re on the “Enriched” tab, i.e. a feed of posts that includes some algorithmically suggested posts. Probably you were switched over to it in an AB test. I’m not 100% sure how you were supposed to find that out. From reading that post, my guess is that via the stickied “LW Frontpage Experiments” at the top of your feed.
So, the reason you’re seeing some old posts is because our recommendations engine thinks you might like them (though I understand the team working on it has put a fair bit of effort towards biasing it towards some of our good, older content, like the Sequences — which seems like a good idea to me, too).
You can switch back to the normal view by clicking “Latest” at the top of the list of posts:
