This is a good example of how news.yc has changed over the last year. Or how continuously growing, unfragmented communities inevitably change over time.
I'm thumbs up on question mark reposts, personally. That said, you can't really knock the original submitter for linking to this excerpt. There's a lot of value in highlighting just the important part...
The first time it was submitted last year, it went to Chapter 5 of the O'reilly book. http://news.ycombinator.com/item?id=34193
This time it goes to an excerpt reposted on a blog.
Speaking of which, there are a lot of good things from the early days of news.yc that should be reposted. Do we have a repost policy?
I don't want to get banned for reposting things by adding an extra ? to the end.
