I know, but the post tab also counstpost the ates to gameew gposted, so it doesn't filter that much if you're following a lot of people or follow proyects that update constantly (like accounts with bundles all year or assets lists that add new assets avery week)
While some people post only games/assets and so on, some other people post this content every now and then and make other kind of posts with critique or jam recommendations and so on. These are the kind of posts that get lost, even when filtering just Posts on the Feed.
