maybe "videos that other stackers recommend" is a specific enough filter.
Yeah, that sounds good
what are you thinking when you mention "more specific post types"? is that like a different consumption experience around video content or something else?
Yes, different consumption experience. For example, if a territory only allows to post images (enforced by a post type), these image posts might immediately show themselves in the feed. So you'd essentially have a image board. No need to click into posts to view the image.
I think we could do something similar for videos. Think of it as something similar to the YouTube feed but inside SN.
