Here it says 7 comments. But you only get to see one. You have to click into the discourse post to get more. This is due to Discourse's threading model. 6 of the comments were replying to the one on the blog post itself.
I see 7 comments when I go to that page. Dig Dgraph fix something in the last hour? Or is the site treating you differently from me because I'm completely unknown to it?
