Or at least have a greater www.stanford-classes.edu, to show all of them.
But the need for a own domain, is to make it easier when the class really starts. Its easier, to use your own domain, that have a leanlauchlab.stanford.edu.
But the point is, its a wonderful news! Congrats Stanford!
It looks like a decentralized movement where willing professors (starting with DB, ML and AI) came up with one platform and different sites and encouraged others to do the same. I am sure at some point they will merge all of them.
It isn't just Stanford classes--the SAAS class is from Berkeley. However, having a hub of such classes from different universities would be really awesome.
But the point is, its a wonderful news! Congrats Stanford!
