Pretty fun overall. The roasts were really good, the stats were pretty neat, the predictions made me smile. The xkcdupe fell flat for me because it's pretty generic and I've seen many variants of it before, but still pretty impressive for an AI to make. The "Your HN Front Page in 2035" was definitely the weakest part for me. Maybe because every gag in it had already been done in other sections.

One thing I noticed is that it seems to give more weight to submissions (i.e. things I've submitted as posts) than to comments (or at least, doesn't let submissions get drowned in a sea of comments), which turns out as a good thing. And it doesn't seem to care about karma, which is also IMO a really good thing, makes it feel like a deep dive and keeps it interesting.
