I think it would be great if this option would be optimized. When I scroll my homepage I read many posts, but I rarely open them. These posts don't count as read, so every time I want to scroll through new posts I happen to find the same posts I've already read, even 24 hours ago.
Furthermore, I don't like being unable to see my own posts when this option is enabled.
Yeah but I'd like to avoid downvoting niche topics just because I'm not interested in it. It would be neat if there was simply a "read" button to hide that particular post. Or maybe just a "hide" button since that's what I'd be using it for!
