(b) most of the code came from existing libraries, APIs, etc
In my opinion the "X in Y hours" articles can be useful. If they can make a fully functional service in a short time due to libraries, those APIs and libraries might be of use for others.
If someone made an article called "Copy of Google Reader in X hours" that used a good JS and feed parser library, it would be interesting to many that would otherwise not know about these libraries
