EDIT: Nevermind. Perhaps it was an ad that I clicked on. Lots of comments here indicating they don't see it, and some that did.
My Original comment here (too late to delete):
Beware. When you reach the end there is a "more projects" button. In there is a cute IQ test (possibly appealing to the HN crowd). When you reach the end of the test it asks for email, and then ultimately wants $1 to get your results. If you pay by credit card due note that there is an auto-checked box for some $29.99 per month subscription for... something.
This is definitely not something Neal would ever do. Can you share the URL you're talking about? There's no IQ test in his projects list at all. https://neal.fun/
