This is encouragement to me (and I hope more people) to develop hobbies of data curating. Such information is just plain helpful and fun. I've never done it yet, but Wolfram Alpha seems to take volunteers (http://volunteer.wolframalpha.com/).
Isn't that basically this article[1] posted to a different site?
Yeah, it's a dupe. Flag it and move on. BTW the "different site" is the author's.
It's not worth linking to the original and updated version of it by the author instead of the wired post about his work?
As much as I prefer to link to the definitive version of everything, in this case since we already discussed the Wired version my dislike of dupes takes precedence. Don't take it too hard; I'm not representative of the general HN membership. I didn't realize it was updated, though.
