Fast moving world when 20 days is "old". What is the time limit? I guess I'll have to start a new thread or just let it go.
Thanks to those who responded.
The time limit is two weeks at the moment. Your article got a good number of upvotes, so many readers found it interesting. Sometimes the comment threads are a small and biased sampling and not representative of the community at large.
We can open old threads when there's a reason, and I think the author of an article showing up to comment is more than reason enough. So I've reopened that thread for you. Comment away! Also, please see https://news.ycombinator.com/item?id=10201327.
