"On a tech/community note, I find it interesting that the blog approach worked somewhat better than the wiki method, at least in the early 2000s."
I am not sure how much grueling detailed work was done on the Wiki (perhaps a lot), ... but what GL really proved, if nothing else, is that hard work matters. GL succeeded because PJ was willing - and able - to put an amazing amount of work into tracking down the details.
She also has an interesting habit of judging uncomfortable issues largely correctly, if harshly - at least those issues that could later be verified, well beyond SCO. One more thing that matters, and perhaps much more easily done on a blog than a wiki.
