I would suggest naming all of the courses, and linking to them individually, too. Technically it's redundant but it's free advertising. It's worth announcing the existence of these courses again (and again and again)... many people reading the blog only just tuned in.

Yes, good point Seth. I’ve added a commit to fix that.

additions lgtm

one further thought: should "doesn’t deliver certificates" be expanded upon? someone just tuning in might not know what that means. if we are hoping that people want the certificates (since it's a revenue driver), that might be worth touting in more detail as well...? not sure

Thanks Seth for your meticulous review! I’ve added a short explanation of what a certificate is. I didn’t expand much, the goal is mainly to announce the availability of the courses on an alternative platform, for people who are not interested in certificates.
