I find it interesting that the piece doesn't cite Hacker News as how the author discovered Iron Python. There is only this: "I’m glad I stumbled on to this project." For whatever reason, authors are generally good about citing other blogs as sources – even just for links, not commentary – but aggregators like HN are almost never acknowledged.
Agreed. I imagine bloggers like John Gruber find a good bit of material on HN, and never reference it, even though he's adamant on citing other bloggers. Strange.
