Right, but some of the comments on HN imply that is the way people think - that most dark matter devs are using old code bases, or don't have the skills to be on the leading edge.
I would see that much more positively: Most of those Dark Matter devs have the experience to know which old and stable technology will be superior to which hyped new fashion trend. So they know about all the new stuff but are still are using old technology because it's the better choice.
