As a portfolio piece, it's great. I don't really care that it's not the most usable thing in the world - the underlying concept is sound, it's easy to see a lot of effort went into the design and execution, and the site looks great! Buuuut that's about all it's good for in it's current form.

Unfortunately, the way something looks is but a tiny, tiny factor in the scope of the overall UX. This totally falls apart as a reference piece that I can bookmark and go back to from time to time. I think this is also compounded by the fact that the content of the site is centered around preaching good UX - but doesn't adhere to it's own advice. I can forgive lapses in UX thinking on software engineering blogs or the latest and greatest crypto forum...but if your site about UX has bad UX, you're in for a bad time - especially on HN.
