I am delighted to see an xkcd comic make it to Hacker News's front page, but also a little disappointed it happened to be this one. It's a perfectly fine comic, but there are so many others that could have engendered even more interesting discussions, which I'd love to have been able to read.
I'm also really missing the xkcd forums. The quality of the discussion was below what I'd expect to read on HN†, but it was still nice to have something for each of the comics.
† No disrespect intended to anyone who was on those forums—you're all great people, but there's less of you, and, well, there's nothing quite like HN.
Limiting myself purely to more recent ones:
• https://xkcd.com/2307/ - Alive or Not
• https://xkcd.com/2224/ - Software Updates
• https://xkcd.com/2221/ - Emulation
