Lack of testing, lack of documentation and lack of use would be reasons that your claim is usually untrue. You can't Stack Overflow a problem and see if anyone else has encountered it before.
This is a terrible reply, what are you even trying to say? You can’t stack overflow a problem so don’t write your own in-house solutions? Lack of testing? We write our own tests. We write our own documentation.
It’s crazy to me how many people on HN are ignorant to the costs of third party dependencies and the benefits of in house solutions when building large applications.
I am trying to say that most of the home grown solutions I have seen have been pretty poor quality, and lack documentation especially. Do enough maintenance programing and you will understand.
If you do test and document your own stuff properly you are in a small minority. Why not release it for others to use?
