You think the original authors (Chad Fowler, Rich Kilmer, Jim Weirich) were ignorant of linked lists? What hubris.

The story is about rubygems, not web dev.

I do? I was saying that being ignorant in CS may lead to lame mistakes, and I have seen many web developers who appeared ignorant in CS, and there has been a case of some central web framework with an O(n^2) queue.

Yes there are many web developer who rely on rubygems, but it was written and continues to be maintained today by people who are (not perfect) but good developers who like Aaron, find shit like this and fix it.

If you actually cared, you'd be out there using your vaunted skills to improve the software other people use, instead of slagging off other developers on Hacker News.
