What do you mean by "posted"? The subject says "posted", but the body talks about comments.
Say you make a video. Where does the video go for the first week? What do you do with it after the first week? Do we host it on Youtube but just make it private or turn comments off, and then the second week, it's made public and the comments are enabled?
Does this apply to articles too?
Isn't the whole point of us creating "content" to advertise, basically? Do we have anybody who loves our content so much that they'd start lurking here just to read/watch something a week earlier? I doubt it.
