All imported comments* on the newly designed blog date from June 29, 2015. Furthermore, they are out of order. In this Winterbash post, it is clear to see that earlier comments are replying to later ones. Maybe some people find reverse chronological order easy to read, though I doubt it, but presenting comments in reverse order with no indication of that because they all show the same timestamp is just horribly confusing.
* It looks like all existing comments were imported into the new blog as part of the static content. All comments henceforth use Disqus.
