Hello, these links have been discontinued (but I am surprised that we notice this only now). What do you think of editing the news to replace this links with text, and adding a note that these courses are now only on Coursera?

Sometimes when a less-important link in an especially old blog post goes dead, I just shrug and change http to hxxp, that kind of thing, just to shut the link checker up.

But in this case, since the MOOCs are so important, it's probably worth actually updating. You never know when people might Google something and land on an old page.
