If that is alright <3

Khan Academy,

I think it would be helpful to display the date of publication on all KA articles.  Then students would be able to cite them without waiting for KA staff to look it up and tell them; it would also help everyone know how recent the article is.

If there's a reason not to display that date on every KA article, please share what it is.  Thanks!
